CAD drawing using Solidworks

I have a product which I would like designed using Solidworks to create a 3d model and CAD drawings which can be used to export to a 3D printing service. The product has two parts and is fairly simply. I have created an actual working prototype out of steel and have photos. I also have 2D drawings I created using Visio which I used to have my steel prototype made. I want to take my existing design and convert it to Solidworks and in the process I will want to modify the design some and will want a designer to work with me to make the changes to design. The end result will be to have 3D modeling and rendering which I can use on a sales brochure and to have a working CAD file which can be used to have the product 3D printed. I would like to work with someone who has expierience in CAD design used for manufacturing and 3D modeling.
