Product Lawyer

How do I service mark a name for a product?
I am creating/teaching a workshop and want to service mark the name of it so it can be used exclusively by me when advertising in print or on the internet- or possibly franchise it later. I probably need a lawyer to do this but any information would be helpful to get started.
