I'm selling monthly 125x125 banner ads spaces on my site at Theme Lab. It receives nearly 2000 uniques a day (sometimes more). Ads will be placed in a prominent location on all pages. I currently have 5 (out of 6) slots open. Priced at $50 / month. More information is available on the advertising page. Please reply to the thread or PM if interested. Payments via PayPal (subscriptions available).
