User Restriction – User Management – User Area

Hi,

I am looking for a way to make a wordpress site a “central” website for local partners – like a franchise.

Say we have the HQ and this “central” website, and we talk about our business on this website and news of the industry etc…

and then we have our local (regional) partners in the towns and cities…

now, what I am looking for is a way to give each of these partners his/her

-individual profile page, and only they or the admin can change anything on that
– they shall be able to post to the “central” public blog, but only after the admin (informaed by email) approves of the post, it is published
– they shall be able to access a public “central” job board to post and delete job offers (very user can add and delete to this job board)
– the admin can offer price lists or tutorials to all users or to individual users in a kind of protected content area

Do you know of a plugin which can do this?

Any hints?

THank you!

Dan
