We are having a client which is looking to develop a service provider directory , which will be provided free of cost to end users nothing commercial for end users they can use it with out any charges.
End users will be able to search providers on the directory and result of search will be show on google maps also end users will be able to search directory pointing different locations on map so directory will show results for that particular location itself.
Everything for End user is going to be free. But the service providers are going to be charged for their subscriptions and that will be minimal plus some part of this charges will go do different charities.
So question is that do they have to take Google Enterprise version? Or Google free version will do?
