Sneaker games Orlando tips for table sales

First time ever going to one of these events. I'm just trying to sell my collect looking to move into a house in the upcoming year. So I'm going to to be giving up on the sneaker game for a while. I've never been to one of these events so I'm wondering from some experienced NTheads if someone can give me some general advice on selling, table set up or any other general tips. Appreciate it in advance !
