I know this thread is a bit old, but you can upload a .stl file to https://craftcloud3d.com/ and they will provide instant quotes with lead times on a variety of printing methods.

I almost got a 3D printer until I found this site. I have used them on many projects using many different processes. All but one have been very good, and that one looked like it was from a home 3d printer because it was the only one I did in PLA.

For the questions above, some of the rubberized or flexible materials would likely work best.
