I need to promote a new self-help book, and hope to get online and traditional media attention, as well as TV and radio interviews. Do you know anyone who is good at getting this for unknown, new authors of self-help books?

He is Esther Williams public relations agent.

I have figured out my approximate living expenses and calculated I need to make $45 an hour to clear $48,000 a year (after taxes). Does anyone else have a better way to calculate for writing?

Thanks in advance.
