Looking for a guest speaker for a women's veteran/active duty event

What better place to ask this than on Rallypoint? I'm part of a military sorority and we're planning our 2015 annual reveille (convention) which will take place in Orlando next April. We're looking for a keynote guest speaker, preferably a woman, active duty or retired, senior enlisted or officer who can speak on leadership/encouragement to women in the armed services. My other committee members told me I was crazy to suggest Adm Michelle Howard, but a girl can dream I guess.

I honestly don't know the who's who of the military - especially over all branches. Can any of you suggest any women that we should consider? To be considerate of their travel schedule, etc, we thought that perhaps it might be easier to find someone who is located within a few hours of Orlando, but we're willing to pay travel expenses if someone is willing to come from further away.

I really have no idea where to begin to research these kinds of speakers, so if y'all could help me out, I'd really appreciate it.

If any of you women who are senior enlisted or officer and would be interested in chatting with a bunch of military sorority women, please let me know! Thank you in advance for your consideration!
