dwarren,
Illy (job description Adobe Illustrator) is always eager to help, and she can help you with a wide range of patent drawing kinds; if you have one or more specific specific kind in mind, you can link to a patent page, or for a sample raster image you can use the Insert Photos button at the top of the Reply box (please abstain from attaching images because they will only be links).
For some kinds of drawings you may (also) consider CAD applications.
