First, if you really want to expand, have 10 to 20 hives with frames and foundation ready to drop bees in at a moment's notice. Then call all your local exterminators and give them your information. Next, the same with all local tree cutters. A swarm in April can, in a good year, fill two deeps and 2 mediums before winter. Study cutouts and trapouts. They pay anywhere from 200 to over a thousand each. That can go a long ways toward buying equipment. Wait on foundationless until your hives are established and then feed them in one at a time, between drawn combs. Find a local fool, er, I mean beek, who will partner with you on cutouts. They are 5 times easier with two, and you will have someone to fill in when you aren't available. Once you do a few, offer free instruction on cutouts at your local club. ""free help"" You will have numerous takers. All bees swarm, treated or not. Most heavily treated commercial hives are not managed for swarm control. They are getting paid for pollinating and "maybe" a little honey, but the honey part isn't that important. In fact, many pollination jobs require feeding and never make honey. The best non-treated hives are taken from a house, tree, or out building where they have been for years. PS. Others are invited to add to this post.
