Like one of the other people mentioned - have you worked on a "proof of concept" - that this is actually a viable concept. The amount of upfront work when developing a franchise systems can be quite substantial - as well as costly. That does not mean you shouldn't research it.

I am not an expert on your particular category (recording studio/music) - but I have franchised two (2) of my own businesses - and many others through my coaching services - so I know what systems you need to have in place for franchise recruiting/development/training/support/marketing etc..

I am not sure of your location - and how far along in your "vision" of franchising. If you could provide more details - I can offer more suggestions specific to your needs.
