One way of looking at it I guess.
Remember owner probably knows little about electrical - hears horror stories about others that were caught, fined, had casualties, etc. Decides to call a professional for consultation on what risk he may have.
Probably is expecting that professional to find problems and make suggestions for solutions, maybe even offer some services to correct such problems. The idea is to avoid being fined by OSHA, and being further investigated in areas other then electrical at same time. Those other areas need addressed as well - but they would likely prefer consultants and not OSHA to point out those issues, which is why they hire them.
