Have a look around on google for print shops in your local area, if there is some, visit them with a version of one of the prints you'd like to do (on a usb for easy travel etc) and ask if they can do a test print for you as your looking for a print shop to get your stuff printed from. It's a fantastic way to find out the quality of paper you'd like, how bright or saturated your images come out, if you need to compensate for bleed margins etc.
