I worked in the paint repair industry for about 6 years. I would say that it's probably not worth it to call a paint shop. Depending on how many chips, and how detailed you want it, it's going to cost you a minimum of $60. Most paint shops when fixing rock chip will either sand it down or fill with bondo... then primer and paint.
Depending on what color you bike is, and the quality of work you want done, I'd highly recommend that you touch it up yourself. Maybe use a fine tipped brush from Michael's craft store. If you don't feel comfortable enough, I'd do it for you.
