The best way to pack with a goat or a Llama is to quarter it like an elk. in my opinion these are just range maggots.
I am a Cowboy as my "day" job and hunter when I get the chance. I would get yourself one good riding horse and a mule that you can ride if need be and then a good pack mule. Haul in some certified feed pellets and you should be fine.
Just my two cents take it for what you paid.
