Design me a Product

I am looking to design an invention and require an electronic engineer to design this product with my guidance. I'd like this done quickly and efficiently. The product will deal with combining kinetic energy (such as in the link below) and designing a mechanism that works similarly but does not violate the existing patent. If this is within your skill set, let us discuss further details, timeframe, and price points through private message. Mainly, the job will require you to design a fully functional system similar to the one in the link. The entire product must be smaller (if possible) than the given sample, and must be able to output a similiar or higher charge to fuel a standard lithium cellphone battery on iphone 6 and iphone 5. Please provide an accurate price quote, time frame, and relevant experience. Please do not bid unless you can certainly complete this project, and have carefully checked the link.
