Will, are you looking to get a degree in Marketing, or are you looking for a course to help you market and grow your business?
I would start with
Strategies for Success offered by
Jon Don. It's the whole package for helping you build a successful business. One day is dedicated to marketing, but the 3 days that Steve teaches is all about "marketing" yourself in front of your customer. You will walk away with so much infromation that will transform your business.
I believe with their new structure, they are breaking the course in to mini segments instead of doing all 5 days at once.
Here is a link to the 5 day class. If you purchase from JD and spend enough, you can get a 1/2 price or even free seat.
