Need to start network

Hi I am just wondering how do these mylikes, fans2cash, skylikes networks work and where do they make money do they have private advertisers? I am looking to make a similar network in future just gathering the information about what are the basics you need to get it started. I know all about making websites. just wondering where their main revenue come from? Your kind information would be helpful and appreciated.

Regards

you need tons of cash to start with OP

Hi Thanks for your reply i do know i need tons of cash to get started. Apart from having enough money what else do you need private advertisers or just ad networks like adsense, Yahoo ads work ?

A friend of mine started the same thing , he spent tons of cash , you need cash for anything and in the first months will end in a negative balance for sure , you need to figure things out

Why not just contact them? Tell them that you're interested in advertising with them and find out if you can buy it directly from them or if they use a network and you need to go through them. It's the easiest way to find out how a company works - just ask as if you're interested in benefiting them.
