Spend time with a commercial person before you get big...way different ball game than a hobbiest
Have a plan on where you are going to sell your honey to
A business plan.
Projected income, then decrease by 25%
know your expenses, then increase by 25%
have a plan in place in case of drought and you need to feed early
have a plan in place incase you loose alot of hives
Set some goals
Always have on hand a sharp pencil, a good eraser, and alot of paper, cost every move out....this is vital and important if you are to succeed in Agriculture.
Bees are no longer pets when you get commercial, they are livestock and need to be treated as such...love the job, care for the bees, let the bees do the work, treat the bees right, know what is going on in the hive.
Be not afraid if the cost to revive a hive is more than it is worth. Shake out the bees, let them find a home and start again on that weak hive. Figure out what $ amount you are willing to spend to get a hive going, then stick to it. If that hive does not produce or get better by a set date, make a decision about that hive. Culling is an important aspect of livestock production...you want your best to give you the best!
Decide your goal...are you a honey producer, or a bee producer...is your market for honey or bees to sell...or queens to sell. Or a bit of each
Good luck
