@jeffcliff With apologies, I don't accept bitcoin at present.
Rate depends on the level of detail you need. E.g. if you have maps already made and basic tectonics, and want to get a reality check/critique, that would be $50/h (one hour minimum).
If you want more in-depth help (e.g. creating a whole star system or planet with detailed climate zones, from scratch), that will be $75/h with a three hour minimum.
Of course, if you have specifics in mind, I'll provide a free estimate, so you know approximtely how many hours will go into your project.

Also: I think there might be room for me to blog (or vlog??) about resources like these! Sort of a meta-review.
Especially since I can tie in other planetary science topics: e.g. how the structure of a planet can (theoretically) influence how it's affected by tidal forces.
Take the example globe in the above video, with a large, north-central latitude supercontinent. Not only will that formation profoundly influence oceanic and atmospheric currents, but if the planet is orbiting closer to a smallish star (late K to early M dwarf), it's more apt to become tidally locked... with that land mass in perma-sun!
