WETT certification canada

This is for the canadian inspectors. Im looking to offer Wett inspection and found the courses that I need to do but my question is it also says that i need to work for a company for a year (ish). I have not called around yet but i kinda think no one will hire me part time while i work on my inspection and also ill be potentially taking business from them. So im wondering is there another way to get your Wett cert or is that the only way?
