I don't know of any books that are specifically on using NLP in marketing. On a basic level, any good course on language patterns would be helpful. "Advanced Language Patterns Mastery" is one of the best. Ross Jeffries has a "Speed Marketing" video course which might be useful.
For marketing info that is not specifically NLP but from people with good reputations do a search on Gary Halbert, Jay Abraham, and Dan Kennedy. You will find books, courses, and some free articles. It would also be a good idea to get on the mailing lists of Ross Jeffries, John LaTourrette, and Kenrick Cleveland and examine the sales letters they send out. Ross and LaTourrette are especially good at this. Do the same with mailing from Learning Strategies.
