You Don't need a course just a mentor to help guide you through the ups and downs. If my memory serves me well there are plenty of local clubs to rugby, I used to live at southam, look up the BBKA for addresses.
I'm not sure what is around you johnr but try the BBKA (british beekeepers asociation) web site for help
The cost of starting. Well how much have you got, brand new cedar wood hives are upward of £300 pounds plus equipment plus bees which are going for £220.
Boyd has gone in off the shallow end and built his own top bar hive but probably he may have difficulty in controlling them as the year develops. I hope it works but I wouldn't bother with that type of hive myself.
Most beekeepers have what are called national hives, 2nd hand they cost approx £30-70 each and you WILL Need at least 3 of them.
I set some one up last year with second hand hives, jacket , smoker and hive tool for less than £130 he had a colony of bees off me.
I would assume that if you started early enough in the year getting 40-50 honey is feasible but beginners get less as they cant leave the bees alone.
Any one who is interested there is a good bees sale of equipment and bees on saturday at lincolnshire show ground I know it is too late but if interested I can get prices of what things sold for. I will be there all day. Do not buy without taking advice as the equipment may be the wrong size or too expensive. As for bees I usually have a colony or two for sale at a lot less than £220.
If you keep bees you will need to keep 2 colonies to help support the other colony if problems develop. 2 colonies takes 1-2 hours a week in April-mid July, plus honey extraction and processing. the rest of the year once or twice a month may be all that is needed. You do not need to buy two colonies but you should be able to split your bees in the summer to produce two colonies. Most beginners usually borrow equipment to extract honey and many local associations have equipment just for lending.
As I have previously said keeping bees is easy The principle KISS keep it simple stupid is what I use. beekeeping is part art part science but in the end 1 years beekeeping is better than 10 years of reading how to keep bees.
let me know if you need any more info.
