Looking for Documents Describing the Client Relationship Team Structure of Investment Banks

Hi --

I am writing an article on investment banking, and specifically, on the way investment bankers work in client relationship teams. I want to describe the teams and how they operate -- i.e., typically (as I understand it) various relationship managers work with various product specialists to pitch clients and meet the clients' financing needs.

Can anyone suggest documents that might be available to members of the public like myself, which describe the client relationship team structure at various bulge bracket banks? I'm interested in organizational charts, press releases, handbooks, fact sheets, websites, training manuals -- whatever. I am also interested in interviewing people informally about the internal structure at their investment banks, if possible.

Any suggestions you have mave for me would be a great help.

Thanks! Joe
