Hi, Sugarplum, welcome to PsychCentral. Check here with these folks:
http://www.metanoia.org/ for online, email therapy; but PsyChris is right, your insurance probably won't cover it if it's online versus face-to-face.
I imagine whoever diagnosed you with the ADD might know of some therapists in the area? Did you ask that doctor?
See if CHADD can help with some ideas:

Or maybe the adult AD/HD association:
