Redeye you are correct, the FTO may well be the sticking point.
I had someone come to me to do my PPL(H) - in the UK.
On the license application form there is a space for the name of the FTO, in other words your instructor would need to be associated with an approved FTO for your training/license to be valid. I would make sure of this and have a written assurance of this (and cost) prior to taking someone on.
