Re: My first two hives of 10,000 have been ordered :)
you will need a whole bunch of empirical knowledge to make it solely on beekeeping. I suspect that any endeavour of man takes years of experience to master, whether it's woodworking, baking, masonry, or any other thing. Expect to be delayed, and stage your plans so that you have backup if something unexpected intrudes.
Best of luck....
