Best practice in setting up an iTunes Connect account for my business

I have a personal iTunes account but I want to create a separate business account so that I can sign up for iTunes Connect to create books? Any suggestions? Should I create a new iTune account or not. I would like to keep them separate but I don't need any of the other iTunes offereings such as music, etc. I just want an account so that I can open the ITunes Connect. Has anyone done that - with or without separating it from their personal. Actually, I have two businesses which deal with publishing so I would probably want Separate iTunes Connect accounts for both of them. Help?
