I'm glad you figured out the picture posting -- and you can even embed them in the text which is something I haven't gotten down yet.
I would also second the suggestion to look at maybe getting an estate sale/auction company involved -- looking at the general map around Lawrenceville, I see several options including "A Perfect Piece". Just as you introduced yourself to us, a similar introduction or mention of "a quilter's house, complete with long arm set-up, sewing machines, lots of fabric, etc." It can seem like a lot of money to go for a professional, but they know the market and going rate and can do most of the work for you, most operate on a flat fee + percent of proceeds so they want to sell high too. There are also more work for you options -- I used to get a lot of stuff from MaxSold, which is sort of a hybrid between ebay and garage sales. Sadly, they don't operate in my new area. Finally, there are places that specialize in Long Arms, like Long Arm University. Looking at their Machines for Sale page can give you an idea of some of the things you will need to know about your set-up:

I recently moved from a house I was in for some 30 years... it is a lot of work to clear out a quilters house! Wish I was a thousand or so miles closer, I am in the market for a long arm.
