Damn, i'm kinda fucked up and english is not my first language, hope all these makes sense

Is there any already built script solution that will allow me to do this:

For example, throwing 30-50 or more domains on a dedicated server, and being able to manage all the ads on them from a single interface (divided by niche, etc) + build dense keyword rich seo pages with the hability to customize, in case it's needed, each one of them via an interface (to avoid se spamming and crappy sites) + let me add content (pics, vids, stories, templates, etc)

I'm thinking on something that will build dynamic pages, don't know what would take a script to rebuild a shitload of .html pages each time i need it or if it's even worth it, probably .php would be better

In what price range do you think a custom solution for these will be?
