Need Advice Finding CPM Network

Hi,

I have a small budget of few hundred of dollars for my new company, it's really hard to get links and traffic,
the Facebook CPM is just a scam, I tried to put $10 and they give me 7 clicks for one day, I didn't tried Google for now.

What you suggest me to choose as CPM network for my web hosting company?
What you think about buysellads.com ?
I don't know how to begin and where to start.

thanks.

Read, test, fail, wash and repeat. Try that formula until something sticks.
