Pricing businesses is not really in the realm of tools because each business is different.
Generally speaking when you sell a business you are selling future profit. So the buyer puts up capital, and figures out how much return they get. They factor in things like effort required, future length of the business, barrier to entry, and so on.
From your description you have something that requires little effort, but which equally has a short life span and is easily duplicated. So worth something, but not a lot.
But I'm assuming a lot of things you didn't really say.
