I am looking for an experienced drafter, artist to sketch in detail a product invention I have. Before I can provide exact details about the new invention the artist must sign a non-discloser agreement. Experience drafting inventions to file a patent would be very helpful. The invention is not large or complicated, but the draft must include dimensions and multiple angles. The art can be done via computer or free hand and scanned in. Please provide come samples of similar work before bidding.
