I've gotta be terribly honest with you... that the art of sales is something either you have or you don't. MCA is a niche: the verbiage, phrasing etc can be taught with minimal effort. What you should do is what I learned a long time ago and find folks who have an natural, God-given talent and implement the specifics.

Probably mad taboo what I just said but I'm too seasoned to care. Best of luck to you.
