We recently videoed a full PDC and appropriate technology course. People can now watch the full PDC for $125. If you make an affiliate link and pass it around, you would get $50 for each sale. If you have a blog and you post it to your blog, that link might bring in hundreds of dollars per year and you don't have to do anything more.
