Innovative Product Mockup

I am part of the founding team of a new consumer products company. We are looking for a graphic designer to mockup our product. While there are not similar products on the market today, we can describe it in quite a bit of detail. The images will be used in investor presentations, on our website and in marketing materials. We are looking for a fairly quick turnaround. Deliverable will be a final print-ready and web-ready image file and ideally 3-4 variations of it (showing different angles, etc.).
