If your willing to have a online company do the prints for you I would recommend a company out of New York called AdoramaPix, part of the Adorama camera store. I've had quite a bit of work done by them (books & prints) and have never been disappointed. Since I live in a border city I have access to the postal and courier services in both countries, thus orders from American companies are sent to Soo Michigan for pickup. Right now the prices for single copies of 8X10 are $1.50, 11X14 is $4, and 16X20 is $10.00. The shipping cost for large prints is $7 by U.S. mail. They say the processing time is 5 days and delivery is 2 to 4, however, I have found on all my orders they have been quicker. But, none of my pints have been oversize. So, 2 11X14 prints would cost you $15 delivered in about a week. Don't know what your cost's would be in your locality but here in Soo Canada the same items would cost a minimum of $25, and although delivery is a bit quicker, the quality is very much poorer. This is the cost at a local self serve camera shop (Black's Cameras and Photograpy). Have never priced a local Color Lab (custom prints) but can only imagine what their prices would be. Hope this is of some help.
