Hi All,
I used a bit map image to vector software years ago called Imagero. They have since been bought out by Graphic Tracer. The new GT software is much more powerful than the old. If you have a decent image you can convert it to vectors very quickly. See the attached original JPG and image of the untouched AI file I got in about 15 seconds, it even did an automatic color seperation. It's not perfect but a great point to start minor cleanup. The software even identifies the font used in the file. Graphic Tracer is running a 30 day free trail right now. You should check it out.
