I will make a 3d model of your idea and can eventually turn that into a 3d print or a machined prototype. I use a 2d package and a 3d package. We can communicate through email, text, phone, internet, drop box or in person if local. I am familiar with many different types of metal and some plastics. I know how to specify welds and other possible off-the-shelf components that you may want to use in your idea (bearings, seals, motors, etc). I charge by the hour (email for details) so less complicated is less costly.
