i am with homer. you are asking someone to babysit your bees. maybe you should pay them?
i would pick someone who knew about bees. also someone who lived in a good place for bees. other than that...will you expect them to feed for you? will they get to keep any honey?
if i were the bee-sitter, i would only do it if i were not held responsible for the demise of the hives. who knows what can happen in a year?
