Can't start my MacBook pro

Question

Good day.
I ask your help.
I have a MacBook Pro Intel core i5 early 2011 model MC700RS / A.
So, my unfortunate story begins.
I use my laptop at home, he was always connected to the internet, and so I decided to encrypt a hard drive, in fact, it is also the password to your account. The company apple computers have such protection is called FileVault. I put it. And it was my first mistake.
My laptop was working without any problems, everything was wonderful, as usual except for one "but." If I click "turn off" or "reset", then my computer started to perform some action, and the time came when the screen displays your company logo and just below the logo spinning circle indicating loading, and in this condition the laptop is able to "forever" , that is, until the battery sits. I was puzzled, and I decided to find the cause of all this. At the same service, "answers google", I found the answer to your question, it said that there are two folders, which are responsible for autostart: LaunchAgents and LaunchDaemons. They are inside the library. It has been said that if you delete unnecessary files from the two folders, the problem will be solved. To delete unnecessary files, you had to take into account one very important detail, delete files whose names do not begin with "com.apple" ... My second mistake is that this little thing I left out. I erased all the files at all. And reboot.
And now comes the climax, when he does not turn on, the situation is exactly as it was before the company logo and the spinning circle. Waited an hour. No-thing.
Reached into Disk Utility, check the drive, all right, to make sure clicked "fix disk" too personal. Reload is not included. Again reached into Disk Utility via CMD + R, as done previously. And my third mistake. I erased the disk partition, hoping to reinstall the OS, but my expectations were not married success. In the end, I got the "not working" laptop with an encrypted disk. I can not add or remove sections, can not install OS, Disk Utility is open only "first aid", and to "erase", so to speak, in gray and the utility says that the disk is protected, and to change or add information / delete partitions, I have to remove the protection.
3 my fatal errors by which I was without a computer. Tried to reinstall the OS, but the computer does not see the hard drive, does not see it, because he is protected.
If someone has an idea how I can build something, please write.
In about the service do not write, I will not give it back, do not trust.
Thanks in advance

Take it to a local PC/Mac specialist in your area is the best advice I can give.
