For the surface, I would take the CF advice of looking for stall mats. You can probably get them cheap at a farming supply store if there is one in your area. Or you can build a lifting platform for fairly cheap if you find the plan online.
Regarding the rest of the equipment, all I can tell you is that if you can't find stuff on craigslist, then MDUSA is a good bet from a price standpoint. Rogue used to be good, but I don't know what their prices look like now. Elite FTS is pretty high priced on a lot of stuff.
Depending on what else you need, Perform Better has got some good stuff and their customer service is outstanding. I would get rehab type stuff from them if it ever comes to that.
crap, I just realized this thread is 2 + months old
And if you don't think kettleball squat cleans are difficult, I say, step up to the med-ball
