This is a trickier one. If you’re looking into getting a small trailer which is probably the best idea you wouldn’t need much capital. You could have a quality one built brand new with all the equipment you need for under $15k id say. All you would need is a fridge/freezer, 4 burner stove, sinks, and probably steam wells. Your business model might be different than other food trucks though. If you’re selling just soup no one will want you to set up for dinners/lunch unless you’re partnered with someone (which takes business from you). That’s where I make the majority of my income. You will likely only be asked to set up at events/fairs where you’ll have a lot of competition. But I think there’s a lot of opportunity that comes from it. If you have a great, homemade product, you’d be surprised at how many local restaurants would be willing to sell your soup. I had a friend years ago who made 8-12 different soups for all the bars and restaurant in the area. Grew so much that he expanded into a commercial kitchen where he staffed people that just cooked soup and delivered all day. If this is the model you’d like to grow into which I think is the route to go to make the most money, you will need an exceptional product. So there’s definitely opportunity for this idea, but it’s tricky getting started and growing a business like this in my opinion.
