I found this site today and must say I can see myself using this many times in the not too distant future. It is an online machine shop. You download software from their site, design your part, and then upload the design. They will then manufacture the part using several options for the process to be used. You can even have multiples of the part made and get a nice discount on the multiple unit order.

eMachineShop is the remarkable new way to get the custom parts you need – the first true online machine shop.
