Army Wife who wants to be a travel nurse.

hello i have some questions and maybe you guys could help. first im a army wife and my husband is deploying in sept 2008, i plan on going home while hes gone cause i have no support up here and i have no kids. Home is MD area. i want to try travel nursing but only like local travel nursing. is that a good idea and then i will continue to travel nurse but only local travel nurse for each duty assignment we get. ie. we are in alaska now so when he comes back from iraq i would want to local travel in alaska, and then wherever else we go. i could still get the stipend that most companies offer for housing. does that sound like a good idea.
another question i have is i have 13mnts experience in med-surg because im a new nurse but i want to go into post-partum/couple care if i go travel, do they allow that or do i have to totally have at least 1 year experience in post-partum prior to joining. i do have some slight experience because before i was a RN i was a nurse extern for mother/baby unit. is travel nursing for me or is it a bad idea for my situation? also can i have a list of travel agencies that are highly marked so i could start my research, what should i be looking for, whats good whats bad. thanks for your advice.
