You're absolutely right about the pricing. Right now it's still in the "throw a number down on the front page and see if it sticks" stage of pricing. I'm still banging my head against the wall to find a better pricing scheme, but it will likely be similar to what you mentioned.

Here, I'll write it down just so I can get it out of my head. :)

* Hobby: $4/mo (paid yearly), limited to 1 site and 1 recipient

* Startup: $10/mo, unlimited sites, unlimited recipients

[Custom Branding]

* Freelance: $35/mo, custom branding, 10 sites

* Studio: $85/mo, custom branding, 25 sites

* Agency: $150/mo, custom branding, 50 sites

It's a lot of plans but maybe the two-bucket separation would be manageable. Or maybe I need to do a more fluid $4-5/mo/custom-branded site plan, but pay-per-use plans typically doesn't perform as well for non-developers.
