Am looking into this as a 56 year old with help from my 18 year old daughter who seems interested. What is the cm language abbreviations. Would love to know. I would like to help physically disabled childern, would you get referals from the council ect for this. Also I have a family friendly, small 8 year old dog. Would that limit potential clients. And how much can you earn before the tax man gobbles it up !! Would love a response to my questions, Plus, I like swimming, do parents happily pay for this, just for there child ect. Or would you get discounts from the council ect.
