Since you are thinking of becoming your own boss and know what area you would
like to get into (weddings/event), I suggest you try (or keep bugging) all of
those catering businesses in your area. Also, I have heard that hotels and
convention centers do hire "inexperience" bartenders for on-call event
bartenders.
That way are getting the business experience you want to learn and bartending
experience you need.
