You could contact the British Beekeepers association (I think thewir website of BBKA.org.uk or similar), and give them your area/postcode for the nearest group. There will be a fairly local one I am sure. Lots of them up here in Scotland.
Become a member and they will amost certainly have summer mtgs at poeple's apiaries, so you meet people and learn at the same time. Courses are usually throuth the winter, but I have only ever attended a one-day beginners course a my local group, and then read books and "shadowed" a beekeepers for a summer. Best thing to do. Stock is incredibly difficult to get hold of atm, lots of people resort to importing, but that is worse I think. Wait for a local nuc/swarm or when someone is giving up. If you can get second hand equipment make sure you disinfect it properly, some diseases spread like wildfire through equipment being sold.
You will probably need a beesuit to just go and visit apiaries, there are companies on www that sell good quality ones. An overall is best, but make sure you get at least a jacket with a hood attached, the ones that they sell as hats/veil only often let bees in (they are very good at finding small holes to crawl into and stings on your face will put you off beekeeping for life!). A pair of gloves is also advisable, but lots of poeple use rubber ones.
As to having someone else putting hives on your land, make sure they have insurance cover, and take into consideration public access (better if not next to a main walking route or busy road), but also security, as hives get stolen quite regularly. Hiding them behind a hedge is good, also painting a natural colour (not brilliant white) helps. I would not put my hives anywhere else but on my land.
