Multiple Forum Poster App, multiple accounts/proxies

I have a Windows 2008 Server. I would like an application Designed to Post on Multiple different Forums. I would like the Program be able to handle [login to view URL], [login to view URL], [login to view URL], [login to view URL] I would like the Program to be able to use Proxies and Also save account infromation for the log in and passwords. All websites mentioned above should be able to have multiple log ins, except [login to view URL] I would like to be able to Post Messages into the Program and have it be able to feed the Forums Above in Specific Rooms/Forums, Each forum above has its own style, so finding out how to search for forums specifically and how to display them in the program is all up to you. Please bid competitively. Also, we need to discuss an update rate after the program is done as i am looking to build a relationship with my programer.
