You can still accomplish what you want to do (selling your business model to others) without franchising. Franchising is very costly and very regulated. Developing your UFOC (Uniform Franchise Offering Circular) and registering with each state requires costly professional help (attorney).

Another option is to do this as a business offering instead. It is less regulated than franchising. However, as a franchise owner myself, I can tell you that buyers are much more cautious of business opportunities precisely because they are not as regulated.

You can still attract buyers by developing a good model and pricing it low (relatively speaking). Pricing under $10,000 will make it more attainable for more people. It is still important to have a proven system.
