Webforms, events, notifications on a franchise site

Hi,

I am working on a franchise site for a company, the main site provides general information about all the services, promos, events, etc... offered by the franchisee.

But not all associated stores offers all/same services nor promotions,etc... and so on.

Everything is solved by a number of related webapps, but the problem comes when a client wants to book a services appointment in a specific store.

Anyone thinks that there is another way of solving this than by making an individual form for each store. Selected store needs to be informed about the request...

Any help will be appreciated
