As $14/monht is too much for a banner for your website.
Not really. We currently have around 2150 banner impressions / day. So with 2 banner ads, each would get around 1075 impressions / day. In a month you'd get 32250 impressions / banner. If each slot = $.50 cpm I'd have to charge you $16 / slot / month. Less than 50 cents cpm isn't too much. I read that Fastclick would give you around that much for cpm.
As for your question, we don't accept text link at the moment unfortunately.
Thanks for your interest.
EDIT: Actually now that I calculate it again it's ~ $.40 cpm, less than Fastclick's $.46 cpm.
