I'm still learning but at first look, I think an ecommerce catalogue would do the trick in the interim.
Basically what I trying to do is provide a database of services whereby a list of services is presented and then if a visitor clicks on one of the services then a list of providers will be presented. Then if an entry is clicked on, then that would open up a new page with full description of services/costs of that provider. with options to backtrack to beginning or last level. Sounds simple but as I said - I'm a new boy.
Also is there a template out there that would provide my needs?
Thanks to all who read and all who reply.
