I generally look for a farm or some old folks, and go in, I tell them I am a local beekeeper and I am looking for somewhere to place some hives. I do move my hives regularly, I noticed that there is some nice florals around atm, would you mind if I dropped some hives in your yard?
you get knock backs, some are interested, some want you to keep coming back, and one lady calls me every week to say what is flowering locally,
I give them some honey, I offer to give them X honey depending how long my hives are there. some people just want enough for them to eat, others want a 4-5 kg or more each time i rob hives on their property.
if i am going to keep going back there I leave a test hive, that lets me know what is happening, once it starts building in reserves, the other hives come for a visit also.
you will get your own style, and you will be able to read people before you even knock on the door.
its not rocket science, but first time, be prepard to spend some time and have a coffee and a chat, and you will get better results
