Batch creating new folders?

I am trying to make a filing system on my desktop for all of my clients. I have about a thousand contacts in this business for whom I need to make a folder. They are in a Filemaker Pro database, but I can export them to Excel or Numbers. Does anyone know any way to automatically make a new folder for each of those names? I thought I could write an Automator Workflow to basically take each name from a table or spreadsheet and make a new folder for each (all inside of a master folder called Clients). Automator doesn't allow that though. It requires that you name the folder you are going to create while you are setting up the Workflow. Doesn't this defeat the purpose of creating a workflow for a task you repeat often? I mean how many times does anyone create a file of the same name?

Can someone tell me if I am missing an obvious thing? Thanks. Any suggestions would be helpful.
