I need to have a handful of product drawings traced and converted to clean, high-quality images that will be printed and filed with the patent office. The original images are hand-drawn by the customer and scanned. There are a total of 13 images, and all are very, very simple. In fact, a couple of them are so simple they are a bit cryptic. So, I need someone who has experience with technical drawings and diagrams that can use their imagination a bit (but not too much). For the most part, there are two images for each product. One image should show what the product looks like (and should maybe be shaded a bit, etc. to look nicer). The other image should show how the product works. Descriptive text should identify key parts of the product and indicate the location of these parts with an arrow or line. The font used should be Arial. The final output images should print at around 6 inches wide, at 300 dpi. All text, titles, and other elements should be consistent from one image to the next. Most of the actual products are displayed on the customer's web site, which may be helpful as a visual aid. Here is one sample drawing. If chosen, I will send you the remaining images and the customer's URL. Thanks.
