Request Categories Plugin

I was looking for a plugin that could turn my categories into a sort of categorized link directory for example I have a site with about 2000 wordpress categories

the problem with having this many categories is it really blogs down the server every time a page with the categories on it is loaded so what I wanted was bascially a way to lets say make 50 main categories 200 sub categories 400 sub sub categories and so on and so on basically it would turn your blog and categories into a directory site as well and at the same time would speed up the loading of any one page because there would be much less categories per page loaded

To me I would think that this would be a script that many webmasters and blogers would love to have as it would give each blog a faster loading page a cleaner loading page and a directory site of there own full of there own post I would think this would bring in more search engine traffic as well

by the way I would be willing to pay for a working version of this plugin my email is Miguelmateos69 (@) aol . com without the spaces and the ( ) of course
