There's been many threads on here in the past of the ability to set tax against training fees - it just isn't possible any more. Can't be bothered doing it myself, but just use the search function - you'll find that whilst you may think it's a good idea, the Revenue won't allow it.
Whilst your searching, have a look for group share costs. You'll find that, whilst you dont want to believe it, this scheme is not going to make you any money, will possibly save you a little, but will porbably cost you a fortune.
Sorry to put it so bluntly, if you go ahead I wish you every success, and hope you don't meet a painful financial end.
