Chroma Key Screens?

Is there a good way to buy these for cheap? I would be fine with just a plain colored sheet, but usually you can't buy fabric in dimensions more suitable to this purpose (I.E., all the length you want, but a similar narrow width). Any suggestions related to this procedure are welcome too, I just need a cheaper alternative than the $25 pieces of fabric I've seen floating around (and something local would be even better).

+ wall. That about the cheapest you are going to get.

Most of the "trick" to chroma-keying is you need to have the key color evenly lit. You may have to use a defuser to scatter the light evenly. (It's those reflective rectangle things you see people holding)

Would you have any good suggestions for a "prop" wall then? I don't necessarily have enough space that I can completely dedicate an area to being green, but I could definitely paint a surface as long as it was removable.

A blue tarp on some sort of tension frame, or even taped to a wall?

That does sound good. Would Home Depot be a good place to get tarps or is there somewhere better?

You can get away with a lot of different materials. The important thing is that the color has to be completely even. And you don't want any of the light on your actors or whatever to fall onto the background. You gotta keep 'em separated.
