If I harvest a deer... I too would like to learn to do this on my own. For a couple of reasons: want to make sure I get the meat from MY harvest... I don't want to PAY someone else...AND you never know how "sanitary" someone else is while processing your meat unless you watch. I have never done it myself... watched a couple of times - but I did see several good "how to to's" on YOUTUBE today. I would start there....
Videos are helpful.... Good Luck.
