Absolutely there are many, many companies you can sign up with. Look at the bottom of this page for the list of companies. Also, keep in mind that with Coyle they prefer some experience, and to do many of their resorts and hotels you have to do some phone or restaurant shops first. They also require a lot of detail with their reports, and as a teacher I am sure you can handle it, but it's best to go ahead and start small to get a feel of how this all works. I recommend starting out with Marketforce or Bestmark before jumping into the deep end.
