How much work/traffic would it take to earn $1 a day?

Sometime you get it from one click.
So,how can i tell how much traffic you need.

 

Depends too on the source of traffic. Traffic from Social bookmarking sites are harder to convert into clicks as they could be just browsing. I find it very hard convert any stumbleupon traffic.

 

buy some good paid traffic...Who knows maybe it might convert for you...
