A good instructor can take you a long way in a shorter period of time. If I can help in anyway, let me know.
Check back to my website often. I will soon be adding video and audio lessons. Some will be free and some will have a membership fee. I also offer remote lessons via a computer camera. You can use a service like skype or Ichat (for mac users).
If those options don't work for you and you need one on one close to where you live, try your best to find a good banjo teacher who can teach correctly.
All the best and let me know how things work out for you.
