Dylan,
Given the relatively small number of skilled engraving instructors in the USA and the relative dispersion of locations, don't expect to find one in your back yard. However, a very fine instructor is located in Gardena, CA. John Barraclough has taught hundreds of people engraving. Here is a link to him:
