I am Matt with WebSponsors.org. My company represents a leading provider of online education. They would like to purchase ad space on your site's page - blog.datacollective.org/
It would look like...
"data mining degree"
with a link to our client's site. We can pay you $65.00 via PayPal as soon as an agreement is made for this ad space.
Please let me know if you are interested. Thanks for your time & consideration.
