Hello.

I have any custom modifications neccesary for my links-SQL engine, namely:

1. User Modify
each user can update their usercontent, like username, password receivemail, newsletter, and ventually extra database fields.

2. Editor Request
Each user can request for editor. After request, the content will be post in a database table. the admin can validate/edit/remove request & send the user email about it.

3. Real LinkOwners
Real LinkOwners are not the users but exact the real owners from a link. I can add the extra name & email field in the link table, but I want to set them to receive email, newsletter and mail them by the email system of links-SQL 2.+

4. Editor things to do.
Often discussed in the forum, but a highly neccesary option.
Editors should have a things to do control panel (called dashboard in DMOZ)

5. internal message system for all registered users.

6. option to search for users/editors in search.cgi

I hope that somebody could help me with this options,
and give me some info how long it takes to create this, and the costs.
