If you can afford it, don't waste your time or cash on the classes. If you've been deconning, then you probably have been taking and counting your own smears or at least have an understanding of the process. Contact a contractor and get an entry level position as a Jr. You'll have to put the time in to get your senior status, but you'll be making money as you progress.
You'll find the general concensus is that deconners do make better HPs. Use the experience you've gained as a deconner to make you an above average HP, and for your sake keep your mind and ears open.
Don't settle for watching access as a junior to fill time for senior status, you won't be worth anything to any of us.
Take the job seriously, ask questions, show initiative to take on work other than "routine jockey", or "access queen"., and you should do fine.
Good luck
