I have only been to sales of this type that were hosted by local scrapbook stores. Most of these were central checkout, but one runs it that each seller must run their own table. Each seller put out their stuff, and each seller takes the cash directly. They sellers pay a fee to the store that hosts it to cover advertising; in your case it would be to cover any costs to rent to space as well. I'm not sure who provided the tables, the store or the seller. When I heard that the store was changing from the central checkout to this format, I was skeptical as to how well it would work, but it has been very popular and well attended.
Just something to consider. It takes the responsibility of the money off of you. It's one thing if there's $30 dollars more in the cash box than there should be, but what if there's $30 dollars less?
