My contribution, for what its, worth, is that last time I was in Las Vegas, I heard a band in a casino, with a little Farfisa organ, drums, bass, and a couple guitars, playing "Sloop John B" and a bunch of the other folkie songs that we all got so much mileage out of, so many years ago--I don't necessarily recommend working in a casino, but the money is better than you'll find anywhere else--LV is one of the few places in the US where a musician can earn a living, keep regular hours, and not have to travel--

Then you could play in coffeehouses and such places as Frank mentions above without worrying about how you'll make the rent--

I'll bet that the minute you start playing where folks can hear you, you'll find lots of people who are interested folk music--
