Ive got a client who needs a business site doing soon and it's a really simple concept and would work perfectly in wordpress as it is except that im not sure if this exists already or if it's going to be a custom plugin job!
Now basicly in a nutshell it will be like one of those freebie sites you can setup (a bit like squidoo and stuff too) whereby each user has a page and edit's it in a WYSIWYG editor!
The editor would then in this case be wordpress and they would each get a set number of pages!
The tricky thing is each person needs to buy a page and won't just be given one for free! They then get given an auto category relative to their company name and then can buy more pages (posts) as they need to and then it gives them the option to add another one! But only if they buy it.
The only thing i thought would be rather complicated and probably doesn't exist is disabling the other options except adding a new post would be custom and also a payment per page system too but making it all auto will save alot of manual admin time and user problems too.
So you tech god's first off does this or something similar already exist (i was thinking about an article directory type plugin)? Or if not is this at all possible (easy or hard)?
