Looking for a place to buy paper rolls

I have an urge to print BIG! Bigger than 20x24. (B&W only)

I know some paper come in rolls, instead of sheets. But, rolls are usually 100 feet long and minimum of 300+ (RC) or 600+ (Fiber) dollars.

Due to limitations on equipment on hand, I'm thinking RC.

Are there any place I can get shorter rolls??

Kentmere & Ilford do shorter rolls, typically around 10 metres (~32ft) - These are quite a bit cheaper, for example: http://www.bhphotovideo.com/c/product/818350-REG/kentmere_6004767_vc_select_glossy_photo.html. Failing that, keep your eye on ebay for short end rolls or out of date stuff.

That's more manageable. Thank you.
