If you use WHCC, they can do 30" high by nearly unlimited width (they say 45"+) for $5.50 sq/ft for a glossy or matte print. You'd have to do the foam board yourself, but it would give you your seamless monster print.
Gotta agree with jdpage, hard to beat Imagekind.com. I'm a member & their prints are done using Epson printers and I hear nothing but good feedback on them. They print at 1440 dpi.
Simply Canvas (simplycanvas.com) is the only way to go for large canvas prints. Any size imaginable and the best quality bar none. I have personally tested every format, medium and substrate available for canvas and Simply does it best.
For photo prints I recommend Color Inc. www.colorincprolab.com
Elcocolor offers large prints that simply can't be beat in terms of quality and cost. They have a section called "internet only specials" where you can find large poster-sized prints. If you order less than a certain dollar amount, the shipping is a bit pricey, but the quality is worth it. I got a 20x30 metallic sports print from them that was just superb. And I believe they offer mounting as well.
Duncan Staples. I dont think he really goes into the wedding forum here so you will have to go and find him. he does my canvas and other prints. great stuff. good guy.
The guy that does my printing just purchased a new printer that will print up to 50". I haven't seen anything yet he's done, but once I know it's awesome, I'll send some info to the forum. I'm very happy with what they do for me in my regular prints and albums. Yvette
