I'm lucky as I employ an old friend so i dont have that worry.
Youth are great, but as already said many of them just dont give a damn. Though I have been approached by a couple of local lads which is a good sign as it meant they were intersetd enough to contact me. remember though, that if employing youngsters H&S plays a VERY important role and you need to be VERY aware of current legislation regarding machines etc. especialy PUWER98
A "rival" of mine has just taken on a apprentice and has been horrified at the H&S implications, the lad is not even allowed to use a cordless drill! In addition, in the first year he doesn't even do woodwork at college he does English and maths! - part of Blairs "key skills" campaign.
Remember also that no matter who you employ you MUST have employers liability Insurance - it is a legal responsibility, also that you will have to pay employers N.I on top of his wages. For me that is an extra £15 a week!
I'm not trying to put you off, don't get me wrong. But it is a BIg step as I have recently found out. My prices have had to increase to cover some of the costs. I worry what will happen if I run out of work - how will I pay Tony? What will Tony do if I'm ill etc. etc Tax is a nightmare though it has got easier. These are all things to be considered.
You may well be better off trying to get somebody say semi skilled/ part retired/ keen diyer for a while to see how things go before you go the whole hog..
Good luck though it can be very helpful and rewarding. Let us know how it goes!
