Hey ironalex! If you are looking for modelers to make the actual 3D models, I recommend searching the Project Runs forum. Some people may have already started and if not there are a number of VERY talented modelers who take commissions through there.
You could also purchase a Premium membership through the site and, once you get to 50 posts, you can start your own SERVICE thread in Project Runs to offer your 3D printing services. Until you reach 50 posts, you may want to look in "Want To Buy" frequently to see if anyone is looking for a printer.
