How do we get these two features added to Pro Sites? (they are real show stoppers!)

There are 2 show stoppers for us with Pro Sites.

1. Not being able to customize the payment page.
2. Not being able to take payments before site creation.

It's sooo close to being awesome - but instead is unusable! :slight_frown:
