I don't think any such site exists (or would exist as very few jobs employers want to fully train people).
Try booking yourself on some courses or look in to getting an apprenticeship - the pay is awful but you get some good experience and many big companies (british gas, BT) are really puahing them atm.
Hi Verix, thanks for your reply and advice. However i was really asking for my mum! She has worked in the Print industry all her life and recently got made redundant! She only has a few years left to work, but as she is struggling to get anything else in Print, she is just looking for something easy to pass the next few years rather than training on anything and doing anything too strenuous as she has been doing...thanks again though :o)
