A month-long fast is nothing. Next time wait longer. When mine fast I offer prey less often, e.g. every 10 to 14 days instead of every 7 days, and I offer a slightly smaller feeder. Most snakes in captivity are overfed.
MiceDirect.com is in Georgia. Even if you're not close enough to buy feeders there in person, shipping shouldn't be too expensive since you're so close if you want to purchase bulk frozen feeders.

Also, if there are ever any reptile expos near you I'd suggest going, you might find a private feeder breeder there. They also advertise on CL and FB.
