There's a place in Hilton Head SC called either
The Jazz Corner or the
Jazz Cafe,
Adagio in Savannah GA,
Churchill Grounds or
Sambuca in Atlanta GA.
I'm told there are a couple of joints in Asheville NC (which could be on the way to Atlanta if the tour is going that way), maybe check with Bryan White (I can't remember what he posts under, but his name is in his signature, so do a SEARCH)
Let's see, in Augusta GA there's a place that pays that has a house band (DTimm's) but might be looking for out of town acts to come through and a place that you work for the door (The Soul Bar) but generally brings in $200-400 at the door on a Friday or Saturday night (hey, it ain't much but it pays more than an open night on the tour).
There's a couple of jazz joints in Rehoboth Beach (I can never remember if that's Maryland or Delaware), DC has a couple of nice clubs (Blues Alley, One Step Down) maybe talk to Tom Baldwin (posts under the name T-BAL), he's in the Baltimore area.
There's joints in NYC that are kind of easy to get a gig in but don't pay, some that pay but are hard to get into, and some that you are basically renting the space and they make money selling drinks and you get the door. The BLUE NOTE has a Monday night "New Artists" series that you might be able to get in on, I dunno. But KAVEHAZ, 55 BAR, DETOUR, etc. it's a gig in NYC but yer not gonna get rich.
As far as booking agencies, sorry no personal experience.
But
www.allaboutjazz.com has a section where there are some agencies advertisements.
Best of luck!
Frode Berg solo album released 
) I can immediately say that you're great. Your balanced-groove-concern-when-soloing with tastefull phrasing certainly gets it going.
