old, new idea or old idea revisited

So Nancy and I had this idea awhile back to have an indoor, continual yard sale. We have friends who have a building for sale that is not being used. For the price of utilities and taxes, they would rent it to us and we would in turn rent it to vendors who would like to sell their stuff in the winter. We even talked about providing pick up service for people who a. couldn't physically get their stuff to us, b. didn't have a big car, or c. were lazy. We would give them a table for say $25 per weekend, but they had to be there to sell themselves. For $25 plus 25% (or so) of their profits, we would sell for them, kind of like consignment. So, really, it was the ultimate in convenience, for a fee: we would pick up their stuff (for a fee, like $25), give them a table, sell their stuff, and donate rest to charity. We also would provide a la carte services; we would price their items, organize, etc. We of course would handle all advertising. So you literally could get rid of all your junk without doing any work, and still get a check. And it would be warm. With bathrooms. That you wouldn't have to pay for (has Nancy blogged about how she offers $1.00 to homeowners who let her use their bathrooms?).
Anyway, for various reasons, we decided not to go through with it, but after not yard saling for 2 weeks, I am thinking we should revisit it. I miss yard saling too much! It is so darn cold, and only getting colder!
