Hi Roger,
The first two names you listed I like but they are taken.. bootyourbiz and ebizboosters. Since I will be offering e-business courses and e-business online promotion tips I really want a name that can reflect what I do. I like something with e-biz..but i think tune-up and on steroids are too different to describe what I would do.

Do you have anyother ideas for catchy names?

I have just a few more I have come across on my search are:
ebusinesstoday
sticke-biz
chetahbiz

Let me know what you think!
