Best Mailing Manager

I am seeking the experienced PHP and Perl coder who would be able to develop the best web-based mailing manager that is similar to: [login to view URL] [login to view URL] [login to view URL] [login to view URL] (Enterprise) [login to view URL] (ugly, but great bounces features) ## Deliverables I am seeking the experienced PHP and Perl coder who would be able to develop the web-based mailing manager that is similar to: [login to view URL] [login to view URL] [login to view URL] [login to view URL] (Enterprise) [login to view URL] (ugly, but great bounces features) I like [login to view URL] interface, but I like other features used by other companies. In other words, I want everything into one system, that will allow for bounce removal management based on rules (look at add2it), templates using wyswyg editor, subscribe/unsubscribe by email ([login to view URL]), etc. The email distribution with email throttle options (number of emails per second, restart automatically if stopped, etc.) should be considered. At last, the GUI design should be php/ajax based, and should look really good.
