Plenty of people want your moving boxes. Have your agent send an email around to her office and within 5 minutes, you'll have people that want your boxes! You can arrange to leave them outside, beside your home so you don't have anyone coming to bug you while you are organizing.
Someone had recommend Sweeps.com to me. You go on the website and "hire" someone to move, unpack, clean, etc. The people are hired by Sweeps so it isn't like a total stranger coming.

Daughter hired a couple of movers for this weekend so we'll see how it goes!
