Server Technology

Hello,
I want to develop a server for my company which deals in Online Advertisement Networking. The server should be able to receive advertisement banners and return the number of clicks, impressions,etc. A huge database of publishing sites, advertisement sites and agencies dealing with us needs to be maintained.
I am a student and though am equipped with knowledge about servers, I am not able to figure out how to start and what hardware and programming languages I should opt for. Please be generous enough to help me a way out.
