This is my attempt at creating something that looks at least somewhat like the real sumi-e dragon

It seems more like a beatiful plant with a something else.
But the dragon is also fine. :D

Does anybody want to sponsor me?

Depends on how much you need. And also depending on what you want to draw with it.
If it is going to be another beautiful plant with anything else I would spend more. ^^
