Pay to Blog with Supporter Plugins

I just want to make sure that I have this right before I install.

Here is my goal.
I don't want just anyone to be able to blog on my site. Preferably only serious bloggers.
If I install the Pay to Blog and make it mandatory for them to pay say $1 to create a blog.
Then with the supporter plugin, they can pay more for premium features.

Does this sound right to you?
