ALL of the advice you have gotten here is great, cheap college. If you are interested in the AV industry and want to make anything kinda sorta but not really close to what you were making you need to be in commercial IMO. If you have kids and/or friends you want to be a PM, not a technician. The techs work insane hours (which they get paid well for being a union shop) and make lots of life concessions to make that money. We have one tech on staff that has over 550 hours of overtime YTD. To do that you really have to love it.

If you want to own a company you have to put in time like the tech, but then come home to do paperwork, generate proposals, and occasionally enjoy a meal while sitting for a change. Good luck and hope it works out for you!
