Most goats can be left alone during the day - I leave for work in the morning and come home in the evening and the goats stay in their pen all day
as to what breed is good for you -- either a dairy breed mixed with a meat goat (so as was stated a %meat goat) or a straight meat (boer, Kiko, spanish) goat would fit your needs.
A pygmy is a meat goat but they are smaller (max of 23 inches at the withers) and if you like cute small goats then a pygmy or pygmy mix would be a good breed but their abilities to do heavy labor are more limited but dont let them fool you they are STRONG buggers. Very stubborn little things.
