I'm ready to cash in my frequent flyer miles and give you a hand. It's actually easier to clean and organize when its not your stuff.
I feel for your situation. I come from a family of hoarders and feel the pressure from both sides of my brain. One saying go "ahead get more" , the other saying "clean up the mess".
Stay strong keep doing more everyday it will get there.
Think about having a quilters garage sale...send a notice to every guild in your area. Post the notice for it on Craigs list.
Selling on the board or even E- bay can take too long.
