First off you will probably enjoy it and the more animals you process the better at it and the quicker it will be... My wife and I have been doing it for probably 12 years when I finally got tired of not knowing exactly what was happening to my deer at the processor or even if I got back "my" deer....
Get a bigger grinder than you think you will need... it makes a ton of difference... Victorinox makes some great knives for butchering and are a great deal.
LEM sells a lot of supplies... I buy their bags for ground and it works great... I did splurge and get the taping device... everything else besides ground I vacuum pack and it stays good and freezer burn free for years....
biggest piece of advice... do not worry about making some mistakes... you will learn and will have a far better product than from a processor... and you know exactly you have your animal and everything done to it
