my wife has been working with a company (http://www.caringtransitions.com/) and this is exactly what they specialize in. Feel free to check them out or give or a call or text. Her name is Amy (832.724.0394)
Hey there, I'm Amy, with Caring Transitions. We offer everything you need to make your transition to your new home. Things we do, decluttering, staging, Estate Sales, packing, and moving, and resettling to your new home (unpacking, organizing, hanging pictures) myself and two other women have interior design background.
as far as using Facebook Garage Sale Pages to sell your items, I actually use it, it's great, when the people show! It also takes a lot of work, and patience to do it.
I've had terrible experiences with Craigslist, I will never use again.
Garage sales are good, but unless you enjoy haggling every item you own on your weekend, just to make a little money, it's not worth it.
if you would like to talk more, please contact me.
my email is firstname.lastname@example.org.
