There's already a few established companies in the "cloud" 3d printer market, even 3D Systems (the 3d printer manufacturer) participates with their Quickparts brand (http://www.quickparts.com/LowVolumePrototypes.aspx http://www.quickparts.com/LowVolumePrototypes.aspx). Just go get some quotes and see if you can make a business case doing this type of thing better in some way. Being cheaper isn't going to win you a ton of business, imho. Being faster or better or more personal, or providing unique materials may win you quite a lot of more niche business, though. For instance, for low volume injection molding, Proto Labs are hard to beat as they will do a fully automated quote and give you flow analysis for parts you upload within an hour or two (usually this takes days). Your business would need to separate itself from the other existing 3d printer providers in order to have good success.
