Tricky website template

Hopefully they may be someone here who knows slightly more about this than me.

Anyway, I'm looking for a quite specific website template. In fact not too disimilar to the way salehoo works. Just a simple sign up, pay, login - members only sort of website.

Cannot find one anywhere on the net, of course I could get a developer to code it and all of that rubbish, but this should be very straight forward.

Does anyone have any idea what I am going on about?

You want a forum type website? Link hidden: Login to view

No lot quite, I know a fair bit about phpbb.

Lets say you go to salehoo.com homepage, you are asked to login, once you login you have the supplier directory, forum, wholesale section etc.

Thats the sort of thing I am after. Pre built with a template.

I use Joomla which you can have setup for you at Siteground hosting and I use templates from Link hidden: Login to view.
