Yes, the primary ticket market I would imagine takes a very large capital investment.

I am more interested in the secondary ticket market, which you mentioned. Now you see why I was so focused on "sources" of tickets. This does become the major issue. I can imagine a few sources of tickets, but they don't seem very lucrative. One would be buying from Ticketmaster for high demand events... problem with this is you have to live in the same state as the show, plus there is a limit on the number of tickets per person. Also, any retail source might involve paying sales taxes, which could destroy profit margins... Buying on stubhub.com and re-selling wouldn't make much sense. Street vendors usually only sell on the day of the show... So I'm at a loss...

any advice?
