I agree with Go Writer - Matt Carter is one of the best. He only charges a one-time fee, which I think is better than paying a monthly subscription. Those quickly mount up, especially when you are starting out and probably not making much income.
I did my own training with Mark Ling, who takes a very detailed step-by-step approach as you watch him on video. Also a one-time charge, and you remain a member forever, get all the updates, access to a really active forum, etc.
