Shameless plug for our 3D printing matching service: http://www.supplybetter.com. You come to us with a project, and we match you to the best service bureaus for the job (i.e. the people with the printers, both hobbyist and commercial). I'm the co-founder and mechanical engineer on the team, and you work directly with me as we source your project. Check us out!
