I have some great sponsorship packages available on HTML Help Central (http://www.htmlhelpcentral.com/).
Limited availability: 10 sponsorships available.
Each HHC sponsor will receive the following:
1. 120x60 static site-wide advertisement on the left side of pages
2. 728x90 at the top of all pages: 10% rotation
3. 728x90 at the bottom of all pages: 10% rotation
4. Text link, text description (approx 100 or so words) and 120x60 image directly below the first post in all discussion threads site wide: 10% rotation
5. Site-wide sponsors announcement: Text link near the top of the sponsors site-wide announcement page followed by a small content section with text link, text description & 120x60 image (same used in #4 above)
*Note: there are a small number of pages that do not carry some or all of the site-wide ads.
Pricing is flat-rate with discounts for longer sponsorship periods. 1, 3, 6, 12, 18 and 24 month sponsorships are available. The discount gets down to a really attractive average monthly rate for the 24 month sponsorship.
There is also a 1 Million Webmaster / 1 Million Unique Viewer Guarantee included as a bonus for the 18 and 24 month sponsorship levels.
