Marcus, I would want the temps to be no lower than 45F. Make sure you give them frames with brood if there is any, frames with bee bread and some honey so they won't starve. Depending on what's in the tool box, bee and comb wise, carefully consider what you will use to house them, be it a medium, deep or nuc. You don't want them to have too much space as they will have trouble keeping warm. Hope this helps, if you have other questions, ask away. As for as price, does the guy think there will be a charge? He may not want to pay much or anything if he thinks he can get it done for free. How badly do you want to do this one? If it takes you say 3 hrs to do, I would say a fair price would be in the $125.00 -$150.00 range. If its complicated, charge more/ You could also tell him you'll charge say $125.00 for the first 3 hrs and whatever you want an hr after that, $25.00, $50.00. This is something you will just have to work out for yourself. Treat yourself and the guy fairly, and you both win.
Sincerely, JP
