Hello,<p>I was thinking of offering my services as a programming tutor in my local area (Bristol, UK). I haven't quite worked all the details out yet, but I was wondering if any of you had any advice on how to go about it. I don't even know if there is any interest for it yet, but I plan to start small and do it in evenings and weekends and see what happens.<p>I think that I would mainly be targeting beginners of any age, but perhaps also university students. I would either teach Android development, or just a language (C, Java or Perl).<p>Has anyone here done something similar? Is there anything you wish you knew before you started?
