I need help in starting a blog which i can make money out of too.?

I dont have a blog yet, but I want to start a blog which I can make money out of. I want to know if there are any bloggers’ sites which give you FREE space to make your blog, and on which you are allowed to advertise, give links, put adsense, banners, keywords, etc. and keep all the revenue as if it were your own blog on your own domain name. I was thinking of starting a blog on yahoo 365, but i dont think what i want is possible on yahoo, right??
so can someone pls advise how do i go about this.
two questions basically:
1. can we use yahoo 365 to make money..is putting google adsense, affiliate banners, keyowrd (paid placements) etc allowed on it?
2. which blogging sites allow us to put google adsense, affiliate banners, keyowrd (paid placements) etc on our blog for free, in which we can keep 100% of revenue?
I got an answer that blogger accepts adsense, as its owned by google. But can i put the following on blogger.com too:
1. links to sites that will pay me for it
2. banners of companies who want to advertise on my site and will pay me
3. keyword in my blog entries for paid placements, etc.
4. anything else that you would normally do to get revenue on a site of ur own
