Why not just have them printed by an online lab? I have used mpix.com for most of my prints. They use high quality paper (the type of paper you should use should be based on your own preference and image subject). They will also send you a "cheap calibration kit" that helps you calibrate your monitor to their prints if you don't calibrate your monitor through other means. Plus, the prices are good and they have a large selection of sizes and will mount them for you if you would like with lots of different options and will turn around the images quickly. I used other smaller pro labs but haven't been impressed by the quality and turnaround time.
