While Adventure Cycling Association does not do custom routes, I would suggest using our Western Express route from San Francisco, CA to Pueblo, CO and then the TransAmerica eastward until you want to begin travelling south toward Atlanta, GA. The links for the Western Express and TransAmerica are below.
For the states that we don't have routing in, check with the individual Bicycle-Pedestrian Coordinators for each of them. The website listed below has contact information for all 50 states.http://cms.transportation.org/?siteid=59&pageid=852
Good luck with your trip.
