ManageWP.com like script

I already have an script that allows me to create 100s of WordPress websites very easily, and in three different categories, WP as a regular Blog, WP as a Press Release website, and WP as a Business Directory. What, I need is a system, application or script that allows me to manage all of them in one single place (panel), something like [login to view URL], but more specific for all my needs. I need to be able to choose the category, and the number of blogs I want to publish - lets say 100, but I just want to post in only 30 of those blogs, want do I need to do that. Some of the blogs in all the categories I'll have may share the same IP address (I will provide all the IP address for each blog to these system), I need the system to avoid using another Blog in the same category with the same IP Address. All my WPs will use the same Username and Password, just to make it easy to connect all of them through the same panel. The system is a lot smaller than [login to view URL], and I just need be able to create additional users, publishers and that's it. I don't need a mobil version, or application, but I need to be able to create additional languages, multilingual ready. I don't need the front end, everything will happen through the administration area, but I want a very professional login screen and backend. These are all my requirements, but if you have additional questions, do not hesitate on contact me before you post your bid. ALL BIDS SHOULD BE FINAL BIDS! Saul
