We're moving from Alexandria, VA to Cary on Feb 21st. We chose Beltway Movers
www.beltwaymovers.com
We also got quotes from: Hilldrup, Paxton, and JK. From our research, all of these were highly regarded in the DC area.
In the end we chose Beltway because of price and because of our previous 3 moves with them. During one move they accidentally scratched our hardwood floors. They paid to have them refinished by the company of our choice. You can't ask for much more than that.
Let me know if you have any questions.
