I am selling banner ad space on http://www.fortjobs.ca. It's a pay per impression rate of $1.00 per 1000 impressions. Traffic is 95% Canadian. Message me if you're interested!
The price is listed, you pay $.001 everytime the ad is shown. The site gets anywhere from 20-200 hits per day, so $1.00 can keep your ad up for a week. If anyone is interested in a flat rate, I'll do the first month for $5.00 flat. You can try it out, and see what the conversion is like. You wont regret it!
