Where can i hire backdrops?

[kali]

Can anybody tell me where i can hire backdrops?

I have come across various sites that loan theatre back drops ect. I am looking for a plain white/grey back drop with industral detailing eg. brickwork, cracked paint ect.

Its for a uni photoshoot, for a Autumn/Winter clothing collection.

Any ideas will be great.

Thanks
Kali
