Looking for custom log-in work

[glenvw]

I am looking for a log-in system that will be low maintenence as new versions are released.

Site: http://www.yes-its-free.com

When people access the board, I want to host a separate page where they log-in or are asked to register. Each time a person leaves the site (closes the browser) I want them to be logged out so they are required to log-in the next time they want access.

I need to monetize the board so if I can make people log-in each time, I could present them with an offer they were forced to see. Ideally, I would like to see after they log-in, that they are forwarded to an "ad page" with a current offer and if they decided to not accept it all they did was click on a link that moved them to the board.

As far as the registration process, I want to collect First and Last Name, City, State, Zip Code, Country, IP address, Date stamp.

I then need to be able to export the member's data in csv or text comma separated format so I can occasionally send a newsletter. I would love to use the boards mailing system but I do not believe it meets the criteria of today's mandatory removal options.

I do not want people to be able to by-pass the log-in page by going to directly to vbbs/index.php .

Also, I would like to intigrate all current members into this without making them re-register.

I look forward to your suggestions and quote for this project.
