GA76,
I think you are letting yourself open for a huge liability problem. Anyone hiring you would be led to assume that you are a professional in your trade. As such any recommendations you give must be accurate. If you give someone advice and they do the work like you say and someones house burns down, there won't bw a corner of the world small enough to hide in where a lawyer won't be able to hunt you down. That said, if you are going to give advice like a lighting layout or some harmless electrical ideas like a decorator would give, I see no harm. But it never stops there. I'd love to give electrical advice, but I've only got 31 years in as a General Contractor, not an Electrical Contractor. So I don't! I only give advice like I'm giving now.
