We sell a lot of our carcasses, but those I keep I butcher myelf..Given most were our small Roe deer its fairly easy.
In the past I used to take some of the meat to a local butcher and he would add pork belly and seasoning ect, and make them into sausages which were excellent...
One time I asked him to do some burgers..Not sure what went wrong, but they turned out like carpet tiles, they were so tough even the dog had trouble chewing them!
Wow, unless you illegally shoe leather cook burger its hard to get it tough...
Burger for us better be medium rare at the most...
