We have a reverbnation profile. We get our bookings through emailing people/venues like you mentioned. Business cards were the first thing we bought for promotion purposes. We make flyers for some of our shows, but not all of them. We've noticed that flyers don't really bring in the crowds anymore (at least where we're from). I take care of our design stuff for flyers and stuff. If there is something "artistic" we want done, like a logo, we go to a friend of ours. Right now we average about 2-3 shows a month. We get the same people coming though like I mentioned. No new faces other than the people who are local to the bar/venue.
