What benefits come with sponsoring a clear sky chart?

Public benefits

When anyone sponsors a clear sky chart, all users of that chart, even the non-sponsors will see:

Removal of advertisements on the clear sky chart page
Earlier data updates. Updating all charts can take up to 3 hours. Sponsored charts are updated first and are typically completed in the first 10 minutes of each update cycle.
An extra cloud forecast. Cloud cover data from the European forecast model, ECMWF, appears on sponsors charts. It's both a backup in case data from the Canadian Meteorlogocal Centre fails and also a redundancy check on accuracy.
Longer cloud forecasts: up to 8 or 9 days into the future.
4 to 6 updates per day instead of 2 updates for non-sponsored charts.
Higher reliability on average. In the event of a server or data link problem, sponsored charts are much more likely to be updated. If something prevents me from updating all charts, I always try to update all the sponsored charts.
A record of past charts: Last two weeks of previous clear sky chart images are saved online. Example.
Detailed climate statistics specific to astronomy, called the "Climate/History" page. Example. Used for scheduling events and site selection.

All of the "public benefits" above
Listing of the sponsor's name, or dedication, on the sponsored chart's web page.
Link to non-commerical website or astronomy-club website.
If the sponsor is one of the top 5 sponsors in their state (or province), listing on that state's (or province's) page of chart listings. Example
If the sponsor is one of the top 3 sponsors overall, listing and linking that sponsor on the clear sky chart home page. Link

All of the "individual sponsor" benefits above.
Link to commerical website. Optionally, a "do follow" link for SEO purposes.
Display 200x50 pixel commercial logo.
Invoices, if requested
Bulk sponsorship of many charts at once.
Timed/scheduled sponsorships, used indicate sales, special events, or to align with astronomy events like star parties, eclipses, etc.
Rotation of 200x50 pixel logos from a set logos.
Extra setup and analysis services, like automatic selection of charts to sponsor based on criteria such as popularity and distance from location.
The general public knowing that business is cool enough to benefit all chart users.

I list individual and club sponsorship of one chart for us$5.00 a month. Commercial sponsorship rates vary based on details.
