Mechanic Job in Mesa, Arizona

I need someone than knows about small motors and batteries (drills, blenders, electric grinders). $15/hour. Saturdays, for 1 month. I want to design and build from the ground up something similar to a small blender, but for a different application. (Nothing fancy or complicated). The main issues for this product are torque, rpm, voltage, and the possibility of an integrated rechargeable battery. Pay and duration of the gig are negotiable and could increase depending on how much areas of the project you can handle.
