Be sure that the removal includes removal of the honeycomb too. If you use a beekeeper, you will then need a contractor to clean out the honey that has run down, replace insulation, clean up or replace siding boards, etc - so you are going to need a general contractor in the long run. I think the thing to do is start there and let him find a beekeeper to do the removal, so you do not have siding opened up for some time after the beekeeper leaves. Also, contractor has a better chance of salvaging some of the siding that has to be removed - a beekeeper is not an expert at that, particularly with interlocked type plank siding.
Make sure any honeyed siding is THOROUGHLY cleaned, or the honey smell will attract new bees. Also, make sure ALL holes ALL AROUND THE HOUSE that they can get in are closed up, because there will be some bees that do not get captured and removed, who commonly try to reestablish the hive as a drone hive, hoping to attract a roving queen to create some fertile queen eggs. Contaminated material can attract other insects too - ants, wasps, etc, so your cleanup needs to be good. If in doubt, or if a wood based siding, just discard the contaminated ones and replace them. Metal and vinyl and concrete you should be able to clean OK.
