So i have a concept i want to get a prototype for. It's 4 pieces in total, but 3 of them are super easy to make. 2 of them are just flat pieces of 2mm thick aluminum with 3 holes cut out of one and some screw holes in the corners. 1 of them is a 2mm thick piece of aluminum with 2x simple 90 degree bends, 2 holes and 8 screw holes.

Only the interior frame piece is complicated, needing 7 bends, 8 holes cut, 9 additional holes for 9 PEMSERTS (3 different kinds), and 21 screw holes.

I have a friend that says he can make the 3 easy pieces for me. Just to get a prototype, do you think it would be easier to have a company just make the 1 complicated piece i need, and get the other 3 made someplace else for cheaper? Or should i have the same place make all 4 pieces?
