Asked for an HTML site; got an ASP site instead - how to proceed?

Question

I am a web coordinator - I know HTML and CSS. I've used server side includes. I've cribbed some Javascript for pop-ups and rel="external." But I'm really a writer who manages a few sites - they were already designed, I simply manage and build new pages, using Dreamweaver 8.
My department hired an outside company to design a new site for us. We made it clear what we really wanted was art - I could handle the rest, as I'm proficient in HTML and CSS. We worked closely with the designer-it looks great, but went through a couple project managers, and something fell through the cracks.
They sent us the files - they're in ASP instead of HTML.  I didn't realize how big of a problem this was until I tried to follow the firm's "simple" save-as directions to create a new page and it all went to hell. This is very different. They had to talk with my server admin about something IIS. I can't see anything in design view.
Reading through the forums, most questions about ASP are from 2008 and earlier, and suggestions for those who don't know ASP pretty much come down to, "Step away from the web site!" It looks like this is something beyond my current skill set.
The new web site is for homeowners and gardeners - it's articles and links. No databases.
I'm so lost, it's hard to even know what I should be asking, but here's a stab:
Can I "break" these files, taking the design but rebuilding as HTML pages? (There is a style sheet.) We've alread paid for the site. They've charged us again just for a couple emails and one phone call to clear up the IIS thing. We're a tiny department in a state-funded agency - our budget is close to nothing.

Answer 1

I'm pretty sure it contains asp code, but I've attached a plain text document with the first twenty lines of the home page.
Link to the page as they've delivered it: http://gardeningsolutions.ifas.ufl.edu/solutions/default.asp
My hacked-up HTML version: http://gardeningsolutions.ifas.ufl.edu/test/gs_index_solutions.html
(Excuse the "search" box jammed in there; they forgot to put one in so I just pasted our old one...)
They gave us a style sheet and the necessary graphics - I could simply work with those, right? Taking out all the .asp stuff?
We don't sell anything. I'm the only person with access to the site. There is no database. I can't think of a good reason why we need our site in ASP. We just wanted it to look pretty. I don't do pretty.
It does look like I could stand to learn some Javascript and move on from there - dynamic features can be added to an HTML site, right?
