I would like to have a Private Mailbox PMB or PM almost exactly like the one on Scriptlance.
I already have the database in MySQL and it already has users in it. It will work exactly like the one on Scriptlance. Each user has their own page where they login. I will add a link somewhere on their login page where they will click to post a private message. Each member already belongs to a group and should be able to pick the names they want to contact from their group.
Let me know if you can do this, how you will do it, how long it will take and cost. If you have samples of similar work, please include in PMB.
I will also need instructions for installing your script on my site when completed.
