First off, If you want to make money, you need a reputable site. Second, it does not take 2nd grade math to do this. A website is a big responsibility. That is why I want to guide you.
People who have blogs are just that...money makers. they hire inknowledgeable people to write stuff an abuse their advertisers.
What YOU want to do is host a Forum...
A forum is an open community where one creates a username, avatar, and posts their knowledge on the site. They will need an email account, but that is like with every Forum.
If one wants to have advertisements, I strongly caution... beware of malware. That is why you need to have a dedicated IT professional at the site of the servers. If you want to advertise, oh let us say, Newegg.com: You would contact them and make a deal on what price you would wan them to pay per ad per page, for how long, and how much bandwidth you allow them to allocate.
First, I would like you to ask a Moderator if you could contact a guy by the name of JFAMD. He will help you on what you need as towards a server for your site. he won't help you start the site, but he will give you the hardware advise to what you need.
If you have any questions, just PM me or post here.
