As a licensed EC in your area, I'll chime in with my point of view. First I don't have any problems with non licensed, qualified, electricians doing limited side work like fixture installs and other minor work. I did it myself and I'm not going to tell you not to just because I now have a license. However, I really don't know what the market would be for a consultant like you are talking about. I've never had a customer hire a consultant to look over the work before hiring us to do the work, with the exception of a presale home inspection. Are you planning to get liability insurance? I hope so, because when you recommend something as an consultant, you accept some liability that your recommendation is correct. I'm not sure without being a licensed EC or EE if you can get real insurance. I would ask you the following questions:
What exactly is the service you will provide?
What are your qualifications?
Who do you expect to be your customers?
How are you going to find these customers? (marketing)
I'm not trying to be condescending, just curious as to your exact thinking and plans. I actually admire your entrepreneurial spirit.
