(15 X what you think your time and knowledge is worth) + (any rental equipment cost + your time to go get it, set it up, tear it down and return it) + (cost of materials to make any agreed upon repairs + your time to make said repairs) + (fee for the removal of pesticide sprayed bees) = pretty fair price for the cut out.
If you are wondering where the 15 came from
2 hours to scope out the job, this includes drive time
1 hour to gather all needed junk to do the cut out and load on truck
8 hours to make cut out, you will not get much else done on this day even if it takes you 4 hours to do it, but
then again it could be a real easy grab and go, adjust accordingly. I always figure 8 some might take longer.
2 hours to set up new hive, feed them over next couple of days and unload junk out of the truck
2 hours to build the wooden ware that is housing the new hive.
I still always like to go and meet the people first, most times that is more important the even looking at the bees. You can always say you need to look at the job first to accomplish this.
Don't sell yourself short, they want the service more than you need the bees!!
