Where can I get cheap but quality fine art print

Hey guys, I’m a small artist in Albany and I have a debut exhibit coming up, but I didn’t know that you had to make your own prints of your digital art. I was wondering where can I get my art print for a cheap? I need three 20 x 20 and one 24 x 36. I am pretty sure that there is a fine art department at UAlbany but I don’t know anybody that is majoring in fine art right now. Maybe they offer free printing services. I’m not sure.
