Just a little nuts today

I'm trying to get organized and figure out what I need to do for Art in the Park in 2 weeks and I'm going a little nuts. Too many things to consider, too long of a list, not sure of the best strategy and I'm not feeling that great. One thing I am thinking about is getting a credit card account--hoping it would boost sales! Seems most people just walk around with a credit card and no cash or checks anymore, so I guess I have to join the new millenium. Anyone have any favorite credit card services I should check out? I've been told ProPay is good....
