first call all the county extension agent in the county where you live and all those county's around you which you will drive to to remove a swarm, then call all the pest control companies in your area and get on their bee removal list if you will remove from buildings or see if they have a list for swarm removals, then post your info and number on all the swarm removal web sites. that's what I do and can get many swarm and building removals a year. also call local police and fire departments and let them know you will take all bee swarms or removals. I wouldn't do fliers, the bee's swarm and removals happen to far apart and it is a extra cost. oh and almost forgot call the companies that do tree removals in your area, you might have to cut a log in half but you get the bee's ;)
