planet.com can get you a ~12 images per day [1] for a reasonable price. If cost really isn't an issue, I'm confident you could strike a deal with planet.com to place their next few new satellites into the specific orbit you want to up the frequency even more.

What is that reasonable price? It is not given on the page you linked…

Are you looking at a 7-8 figure upside to your deal? It's reasonable. Are you looking for fun? Unreasonable.

I believe 3m res data from them is around the $2 per square kilometre mark, however varies wildly depending on scale

Could you divulge what you use the images for?

Or, anyone who buys satellite images?

I know about real estate, navigation, and I've heard that some business use them to forecast retail sales.

I curious about other uses.

Tracking deforestation, melting of glaciers, basically anything geographic. If you're looking for things people profit from, you're right that some trading firms use satellite images to count cars in parking lots of e.g. Walmart to predict earnings reports. Similar things can be done on oil refineries for example (some satellites can even look /through/ oil tanks to look at oil levels by looking at specific wavelengths).
