Life's been good to me so far

This person may be completely legitimate, but there are way, way too many people out there trying to take advantage of writers who aspire to publication. Rule 1 of legitimate publishing is "money should flow toward the writer." Legitimate agents do get paid, yes, but they take a percentage of your check only after they get you a contract. Any service -- editor, publisher, agent, "coach" or what have you -- asking people to pay for anything out of pocket should be regarded as highly suspicious. Remember, there is no qualification required to call yourself a literary agent -- anyone can claim the title, many do, and any of them who charges you for anything before your book sells is skeevy. The only exception I can think of is classes or workshops or conference registrations, and I would only pay money for those if it was to work with someone I had actually independently heard of outside of the "we can help you get published!" industry, e.g. an author whose books I liked.
