But keep in mind that you are charging for your knowledge and experience. You are doing something that they not only can't do, but they don't have the tools to do it. $80 for a two-hour job might sound good, but it really isn't. The tools are expensive; not to mention the wear and tear on the compressor. I'd love to have my heads and Air Gap ported, but there is nobody around here to do it, and the shipping would stink.
