This is an easy project for someone with good basic computer skills. I'm looking for someone to:
1. Do some basic searches in Google on 10-12 keywords.
2. Go through the top 30 results for each keyword, look to see if the sites sell/offer/display advertising.
3. Look up the sites that do sell/offer/display advertising to see how much traffic they get.
4. Gather the basic contact information for each site's owner
5. Copy and paste all the gathered information into a Google docs spreadsheet.
Total time for someone who knows what they're doing, 2-3 hours.
If you do a good job on this one, we'll potentially have many more similar projects in the near future.
