I'm in a predicament.. Assistance??

Question

Howdy,
First time poster. Better late than never, I suppose.
First, a little background.
For years, I was using a Nikon D60. Plenty fine entry-level DSLR. Then, in April of last year, I purchased a Canon 60D 18-135 kit. I also added the 70-300 USM, a Speedlite 320EX, and a Canon battery grip. I loved it. Shot some great pictures on it. However, a couple months later I had to sell it to fund another situation that came up. Missing out on having a camera, I picked up the Canon EOS M when it went on it's mega sale. For that, I have the Speedlite 90EX, and both US market EFM lense (18-55 and 22). I am formally trained in video production, but my love is photography. I do mostly hobbyist work, but am trying to venture into doing more photoshoots and paid work.
So, my predicament.
I love my little EOS M. I really do. Eventhough the focus issues have been more than well documented, it's a great little camera that takes every bit as good of an image as my 60D did..except for action. Studio work, car photoshoots, nature, etc. It does them all great. But you throw something moving into the mix and it's a disaster. I do not plan on getting rid of it. I plan on purchasing the EF/EFS lens adapter for it next week actually. However, I do realize the limitations of the camera. For the price, it's an unbeatable backup and a great camera to take with you when you don't want to lug around your whole setup to get a decent picture.
Now, where you come in.
I am looking to upgrade my setup. I am looking to purchase a new "go to" and the M will be my backup. And with the EF/EFS adapter, it'll be a good one at that. So, the main issue is that thus far, my paid work is few and far inbetween. Definitely nothing to purchase a camera body with, and barely even a Speedlite. But I'm hoping to change that. Up to this point, I'm completely self-funded. And thus, I'm trying to make the most economical, but well educated purchase I can. I will be using this as a complete all around workhorse. All sorts of photo, as well as video too. My list consists of the Rebel T5i body only, 70D, another 60D, *possibly* the 7D, and the 6D. I'd love a 5DIII, but there's no way I'm able to fund one at the moment.
Here's my breakdown. Feel free to chime in to your discression.
Rebel T5i:
A proven, reliable go-to. Entry level, but has many solid features. Compact, while normally a good thing, fits a little awkwardly in my giant hands. My big issue with the T5i is that, although very cheap ($600 body only), it is more or less my EOS M with a viewfinder and more buttons/dials. It may not be enough of a change to warrant upgrading.
70D:
After having the 60D, I definitely love the siziing of the bigger cameras. The 70D essentially seems to be a 60D on steroids. At $1,100 for body and $1,300 with the 18-135 STM, I'd probably just opt for the kit. Seems like a great camera that particularly excels in video. Seems to be the current king of the crops, until the 7DII comes out.
60D:
Great camera. Does everything pretty well. The biggest bonus here, it's now SUPER cheap. At $700 body only, or $900 with the 18-135, it's a steal. Not to mention $300 cheaper than when I bought it. However, the technology has been surpassed by the 70D, and it may be worth the diference over it's older brother by now.
7D:
Although older, I know a ton of people that LOVE their 7D. It seems like the 70D has taken it's crop senosor king spot for now, but still a great camera. Big issue is it using CF Flash cards. Things are EXPENSIVE. I'd wait to see what's up with the 7DII, but I need to get a camera sooner than it'll be released. $1,400 for body, or $1,500 with the 18-135 / $1,600 with the 28-135 USM. At that price, it seems like the 70D is now also more competitively priced. Not to mention the SD card savings. But is it still "better"?
6D:
It would seem that this is the obvious choice. However, being self funded, $2,200 with the L lens kit is still costly. I would love to dive into the land of full-frame, but I'm still trying to be budget friendly. And with the 24-105, that'll cover most of what I'd need with addition of a couple primes and a 70-200 f/4 L to start.
As you can see, all varieties. Consumer, Prosumer, and Semi-Pro. In terms of my ability, I'm probably wedged between prosumer and semi-pro. I could definitely benefit from the 6D. Especially for what I shoot. But that's still a good chunk of change.
For the crop cameras, I was already planning on getting the EFS 17-55 2.8 USM, and the EFS 10-22 USM. Then either the EF 70-300 USM or 70-200 4 L for my zoom, as well as the EFS 60 macro and assorted primes.
For the 6D, the kit 24-105 as well as the EF 17-40 2.8 L, EF 24-70 2.8 L, and EF 70-200 2.8 L down the line. As well as a macro and some assorted primes of course.
Flash and other associated photo video equipment I'm good on. I am just at a loss of which way to go. Full frame sounds amazing. But then you have the associated cost with the upfront cost and future lenses. But if I stay crop, I can get what I need with the EFS lenses, an EF zoom, and be done with it. Definitely cheaper, but I don't know if it's the smartest choice.
So, I believe I'm done here. Sorry it was long-winded, but this has been plagueing me for the last few weeks. I hope someone else can help point me in a particular position. Please offer suggestions, and I'll be happy to answer any questions you may be able to interject.
Thanks!

Yes, sorry. I did realize I didn't specify exactly what I shoot.
I do a lot of car-related things. Car photoshoots, races, etc. I'd like to delve into portraits and such more upcoming too.
The races are easy to do, so long as you have a fast camera and a good lens. Even going from my old Nikon D60 to the faster Canon 60D proved very helpful. I am also pretty good at the focus pan where you move with said object to blur the background.
My real issue with the crop sensor cameras thus far have been the noise levels. I do a lot of shooting in low-light. But I figure a couple proper lenses a good tripod, and some time experimenting could help that.
I do like the idea of the T5i as it's so cheap. At only $600 on the body, that would give me plenty of wiggle room to fund proper lenses. And I suppose that if I went that route, I could always just end up picking up a 7DII as my go-to when released, since the T5i will obviously have it's limitations.
But at the same time, going right for the 70D would also be a solid choice as to it's benefits, larger sizing, etc.
Although I'd love a 6D, it's probably better that I stay away from FF for now until I get steady pay from shoots. I know me, and I'd take myself broke buying proper lenses.
The 60D seems like it's still a good choice, but kinda going backwards from the others. And the 7D, same thing. Although still a great camera, it seems to (at least for me) have the negatives outweigh the positives at it's price point.
So it seems like it's been narrowed down to the T5i and the 70D.
FYI, I don't have a ton up yet as it's been recently created, but feel free to check out my page for a couple references of what I shoot. It's below.
Also, on Instagram, I'm "averagewhiteboy" as well. I have a Flickr Pro account too, but I don't think I've updated it since going Canon.
