Go back to the BBK guy & ask if they will mentor you or ask can you shadow them for a season at their hives.
If they agree do be punctual , & act responsibly .
Keeping stinging little flies is really quite simple , it's the getting of honey in spite of the attentions of the keeper that matters .
Seriously , a season being mentored on a good 10 hive set up is worth it's weight in gold . You will soon see that if everything you get is of one type of hive & made to standard sizes it's going to benefit you far more than seeing 10 hives that are of all different types that are held together with bailer band , barbed wire & faith .
My mentor a semi commercial keeper harvesting about a tonne honey a year was good enough to let me take my frames to his place to use his electric extractor , hot water de capping table & his settling tanks till I could afford to buy my own .
Over the years Alvin & I became great pals he taught me a lot as he had 19 years lead time on me .
One of the best observations he made to me was that when opening up a hive it 's not worth the time looking for the queen instead look to see what is not right in a healthy hive instead . If you notice a differences /problems then start looking further into things .
