Where to make cheap color copies?

I need to make about 1500 colored 11x16 copies/print outs and looking for a cheap place to do so. Any idea?
Update: It would be 1500 copies of the same page and I already got quotes in but I still think that 35c a copy is to much for that amount of copies. Just thought there may be a online store or someone I haven't thought of. I mean I went to like FedEx staples and UPS and stuff...
