Amazon help needed

I have a recently published book which I need to set up a sole seller account for on Amazon. I need to ensure:
- my seller account is set up correctly
- The book is set up in the right categories
- It comes up with the correct search terms
- The book is nicely presented
At the moment the book is already on the printers account but it is in the wrong categories etc. I therefore need to set up my account, take the book over at which point the printer will take it off their account. This needs to be seemless....
(The printer is happy with this plan)
I am not interested in generic offers as this is a specific project and I want to work with somebody who has fully understood the brief and has all the relevant experience.
