I totally agree that a full craft booth, is the best craft booth. You want to have as much product (without looking crazy) as possible. I did not have great luck with custom orders at craft fairs. I found that people felt better about ordering custom things through a "store" rather then a booth. If someone was interested in a custom order, I would go through my etsy shop. I would set up a custom order for them there, and send them an email notifying them. They would then order through the etsy, pay through the etsy, and I would ship. I didn't get any custom orders, until I started this way. If I were you, I would start out taking custom orders like Momma L suggested. See if that works for you. If it doesn't, you might look into having an online shop.
