Product and system illustrations

We are building a prototype of a very small and thin ECG patch that can be put on human's chest just like a band-aid. We hope you can help us illustrate the product and our system diagram which is in the attachment(FullSizeRender.jpg). Basically we will need a picture representation of the system diagram.

We will need to get this done by Jan. 2, 2016? Is it possible you can get it done by then? If so, what's your estimated hours?

Thanks,
