You could go to a flooring store and buy some Linoleum. The under side of it can be painted and hung from a crossbar to give you a fairly solid looking cyclorama. You need to buy a good 30 feet of it and use heavy-duty stands and clamp the rolled section to the crossbar. It helps if one end is taped to a large cardboard roll to help it roll easily on a crossbar like seamless paper. Paper Seamless can often be uneven and If it's gotten humid it can be wavy and look like crap. The advantage of the Linoleum is that you can paint it whatever color you need. Hope this helps.
