Building a new rda

Right so I've got a design for a new rda and I need to create a working prototype to test, I dont know how to go about this and was wondering if anyone here has any experience in/ know someone that can make small metal parts. Any help much appreciated and any questions welcomed.

Google small parts machine shop, but be ready to pay an arm and a leg. In our sign shop, we charge $125 an hour for routing and that is with wood. Be prepared to pay more than that plus you will need to pay/beg someone to supply them with the CAD drawings they will need to actually create your parts.

On a side note, I always love the look of sticker shock on a client's face when they find out the 3D carved sign they want is going to cost them 3k or more. lol

Good luck in your search.
