Well if you want to tour independently, then i'm pretty sure your going to need fans on a national scale to do that. Signed artists/producers have the benefit of touring with already signed artists/producers to that label. If you have any friends that are touring you may want to see if they'd like to get you in on it. I don't have a lot of experience with tours, but that's my understanding. Definitely do some research on it.
You can also look up any clubs that are in different cities in different states. However, if you go this route you may come up on some pretty desolate nights for the different clubs.
