Looking to design a battery pack, need engineers near Minneapolis.

Looking for an individual or small team near Minneapolis. This project involves a lot of moving parts so I would like to meet face to face on occasion. I'm looking to develop a battery pack, more info in the attached doc. Whoever takes this on needs to have experience in electronics design and mechanical engineering. Able to design in AutoCAD, prototypes on a 3D printer. For fabrication we would likely go to a mold shop. Collaboration with the mold shop might also be needed to get the prototype right. Up to the prototype this is likely to be around a $20k project. Looking to start within the next week or two.
