I understand you want fast track into our world fella but really, I would fall over if I was joe public and I found out the sparky who was rewiring my gaff had got certificates after a 10 - 12 week period!
It takes years and tears to get to the stage where you should feel comfortable and COMPETENT to go out on your own. My advice if you want a quick living - become a bloody plasterer as at least you won't kill anyone!
Good luck!
