Air Cleaner - Product Design

Project Description:
I need a skilled product designer to conduce the final design of my product. My product very similar to a electric Air Cleaner + Vacuum Cleaner.
Notes:

1) The professional must have proven skills on product design: Solidworks + 3d Renderind are MANDATORY.
2) I'll only take in consideration BIDs from freelancers with portfolio OR samples from previous works, otherwise I'll hide the BID from my list of prospective freelancers.
3) The freelancer needs to have knowledge into plastic injection, once I'll require the parts designed, ready to the mold project (mold design isn't a task of this project , so do not add the cost to do it).
4) Although my product is an air cleaner, the design concept is a cube with rounded edges and corners, like this alarm clock: http://www.behance.net/gallery/Snooze-Cube/2568147
5) The main components are electrode, circuit boards (two), vacuum motor with rubber bumpers, and common electric components. I don't have it in electronic format, however I'll provide photos with all dimensions and what be needed to the project progress.
6) A NDA sign will be necessary.

Note: I have a budget on my mind (I will not share, so do not ask). Please be honest on your BID and realistic on time frame.

Happy biding!
