I've sold plenty of text links on my sites, but I've never had a potential advertiser inquire about display ads before. But it happened today, and I'm not sure what to ask for. Looking for some suggestions. The site in question had 35,000 uniques and 80,000 page views last month, has a PR4 and 633 backlinks. I'm looking for suggestions for 160x600 and 120x240 ad sizes, a monthly rate for each. Any ideas? thanks very much
