Great idea by Pay Per Click Advertising.

I think you are looking for a Publisher network. If you can get Adsense that would be best for you. But there are also few high paying Ad networks are available. These are some high paying Ad networks
PropellerAds media
Infolink
Chitika
Clicksor
BuysellAds
You can get highest CPM rate on PropellerAds media.

If your blog has lot of traffic you may ask people directly.But you will have to use some analytics system to track views and clicks etc.I am expecting that you are good in js because on blogs only js can do that, i mean if its a bloggers blog.Other wise if your site is in php then you can easily track such data.

bidvertiser is better i think

Pay per click advertisement is good to go with.
