The system must contain a calendar that is searchable by city to let the end-clients find the right franchisees. It also should be possible for the administrator to sell info material to the franchisees.
To elaborate on what Tony said a little:
I'll assume by "sell events to their end-clients" you mean event attendance registration/tickets. In which case RSVP Pro is what you need your franchisees would create events and setup their registration forms to collect the information/payments they need. This can be via Paypal, Authorize.net or using the payment gateways of Virtuemart (I've not looked at their multi-seller capability closely so we may need to adapt our plugin to support your multi-seller scenario).
Not sure what 'sell info material to franchisees' means - if its 'client only material' then you might want to look at Akeeba Subscriptions to handle that. It would allow your client to sell subscriptions to the frnachisees and these would control the permissions to create events and access rights to client specific material.
re the lifetime membership - its not something we have offered. It makes our accounting very complex since we would be taking in money in one year with a multi-year liability on the other side. All our addons are GPL licensed and can continue to be used after your membership expires. If you want ongoing support and access to new releases then you would renew your membership each year - we offer a discount on renewals (currently 20%).
Sites that offer a lifetime membership cannot realistically offer lifetime support. There are so many scenarios where this would fail - e.g. the Joomla project winds up/splinters into competing projects, PHP fades out of popularity (like COBOL) etc.
