I could use some help. Advice. Direction.

I am just learning about copywriting. Two weeks ago, I didn't even know what it was. Most of what I have learned has come from forums like these and free advice on private websites. Later, I plan to invest in Bly's Copywriter's Handbook*

After reading a Jay White interview, I am considering beginning my venture by way of catalogs* I am planning to find some potential clients that market to those who share my personal interests* Then I will pound out some samples and e-mail a few businesses, marketing my services* I have some advice to go on as far as writing the samples, but I am not too sure what to include in the body of my e-mail* Since I have no experience or website, should I reference my education?* I am looking for help in answering these questions as well as any others I may not have thought of. Anything at all would be helpful. Also, are there any threads on this forum pertaining specifically to catalogs that I may have overlooked? I have read many insightful posts from a number of experienced and successful people. I would greatly value anything offered.

*please make suggestions and/or advise

Thank you all!
