Network of buying traffic from webmasters

Good day.
There is the problem of creating a system for buying traffic for webmasters and pay for this traffic with various options: cpc, cpm, etc.
The repurchase will be made through otkrytku promotional materials on the websites of webmasters in a variety of formats, such as: popunder, clickunder, banners and so on.
Definition of browser, IP, country, region to load the desired promotional materials.
Stawicki calculation on the basis of impressions and ratio to these shows.
Need a modular solution: each ad format can be added or deleted from the system without affecting the architecture.
There is TK, which describes the essence of networks, ad formats and so on.

Who are you looking for and what skills are welcomed?
