Unfortunately there is no crash course and the business takes a lot of time to learn. There are a bunch of seminar hucksters out there pitching this as a get rich kind of deal when in reality it is a get rich, slow and only if you are careful business. We have an industry links section on our website that has external links to sources that offer reliable information on the subject. The links are hand picked by me and will give you a lifetime of information regarding the note business. Happy reading!
