Need CAD Draftings/Renderings of Fitness Product

New product that we need help in designing the architectural draftings for. It is not an electrical product. PVC or ABS plastic based, and the basic overview of what needs to be done including sizes and functionality. We even have a Google 3d Sketch showing the overview. What we need: 1) Someone who can take what we have done so far and make it into a useable rendering with measurements for production and for patent purposes (though there is already a provisional patent on the item). 2) Someone who can also provide 3d rendering of the product together (and its various pieces) so that we can use it for marketing purposes. 3) Someone who has a general knowledge of how this work! Such as push button mechanisms, etc. 4) If you have knowledge of materials such as plastics (in regards to molding and strengths), or rubber in regards to gripping and surface....that would definitely help (please let us know). 5) if you have any suggestions on manufacturers or methods....that would also help if you can steer us in the right direction. We have big plans (we're sure you've probably heard that before), but we have a handful of products to produce...all in the Fitness industry. There could be an opportunity to own a stake in our company! YOU WILL BE ASKED TO SIGN AN NDA BEFORE ANYTHING BEGINS....if you are not ok with this, please do not bid. Please provide samples of your work...and any references. SMALL BUDGET FOR NOW....SORRY!
