I like both folks! Great very helpful. You might want to check both of them out. Call them. One may have more info in the literature department that you might need to know in order to run your business, like things you need to know about bookkeeping and web sites design etc.
Don't get in a hurry. Take your time. I said this before, not having any hot dog vendors in your town is not necessarily a sign that you're going to make a killing. Maybe people in your town don't eat many hot dogs.
I only see one hot dog vendor in my town at Home Depot. I've known him personally for years and he isn't doing great either. It's all about location. Not only the location where you're going to set up, but the location where you live.
You'll starve to death trying to sell Alligator tail in most any part of the US except Florida and New Orleans for the most part. Tourist and the locals in those areas will eat anything. I don't think they will eat Alligator tail in Cheyenne Wyoming.
Take it easy and go slow. If there are 25 hot dog vendors in you town that's been in business for ten or more years and everyone in their family are driving new cars, order a dozen hot dog carts built, and just make a loan.
I'm not trying to be sarcastic. I'm just trying to help you to be more in tune then I was when I started looking into this.
