Flash:
I've had a couple of friends that tried both ends..franchising a business, and being a franchisee. (Being a franchisee of a Dairy Queen operation proved very lucrative for the one; being a franchisor for a metal fab shop not as lucrative, but his business is still ongoing)
Because of that, I'd say that there's a couple of things to keep in mind about franchising a business (being the franchisor) and selling franchising licenses to potential franchisees.
First off:
You need to register your business's brand name, trademark, and, (as David Letterman and the TV networks found out), any "intellectual properties" that might be unique to your business.
Second:
I believe to legally sell franchises one has to file with the appropriate State and Federal agencies their franchise contract agreements and a Franchise Disclosure Document.
Third:
What is the marketing plan for franchising (IMO...differs from a business plan)
Fourth (Looking at this from a franchisee's standpoint)
Why would I want to be a franchisee?
1.) Is this business credible
2.) How long has this business been established
3.) Is this business well recognized
4.) Is there a training/operation manual that's easily understood that will facilitate "learning" the business model (I think fast food operations)
5.) After paying the bills, including the franchise fee, what is the profit margin compared against my investment
Fifth:
Due to our societies laws, and against my better judgement, it is imperative to seek advice form an attorney...in this case, a Franchise Attorney.
Good luck in your enterprise! Keep us abreast of any progress.
(I just might want to get in on this, I really don't want to have to 'make' the wife work forever.)
