Great job on asking questions early and getting things lined up! I can understand your situation, as I am retired military myself and PCS'd several times during my career. Having a school-aged daughter, you may want to focus on the Cherry Creek School District. The Cherry Creek School District is one of the best in the entire state, and also happens to be close to Buckley Air Force Base (best of both worlds!).
I work for Stars & Stripes Homes, and we are located directly across the street from Buckley. While not limited to military clients, many of the active duty, retired and civilian personnel seek our assistance to buy, sell and/or rent homes.
You may find out more about us at http://www.starsandstripeshomes.us.
If you have any questions, please don't hesitate to contact me at 303-326-0550, ext 108. I've been a military sponsor as well, and I'll be happy to assist you with your relocation in any way I can.
