Dog training as a whole

Well, being as this is my first post, let me introduce myself. Im a broke second year college student who spent my first college summer volunteering at the Humane Society of Memphis and Shelby County out in Shelby Farms. I thoroughly enjoyed every minute of it (yes even the cleaning of the cat cages and picking up the dog feces during the dog walking sessions).  I learned that I need to go into a field that deals with animals. I did lots of research on different jobs and discovered one that I could do during college with no problem. I could be a dog trainer. With what I learned about training dogs from the dog walking classes there and from my life experience with dogs, I set out to find someone willing to hire me.
              They get decent money for what they do and if its professional rates, it is possible to get around $70 per hour. Seeing as I am not a professional yet, I wont be charging that amount but somewhere in the neighborhood of $10-20 an hour wouldnt be too bad. That would give me money to eat on each week and possibly let me save up for some mode of transportation. Now I just need to advertise and that is the hard part.

Since this is my first blog, I dont know what to start blogging about. Im going to use this blog to practice writing a researched argument on something I enjoy. So any suggestions would be helpful. I would most likely start with the training methods based on dominance, but give me things you would like to know more about and I will research the subject and write a post.
