Gee if you are looking into it, it is called (SDS) Self -Directed Support, if you google it you will find loads of information on it and nowadays most area’s have support groups with loads of first hand experience, it is certainly worth tapping into them.
I don’t know if you stay in England or Scotland or Wales or even Northern Ireland, but my experience is in Scotland. If you need any advice, feel free to ask me, as the principal of SDS has helped me immensely in my life, but council’s are less than helpful and less than encouraging for you to go down the root of option 1, as it takes trade away from them, that is why you need to contact your nearest SDS support group for advice and help. You will also need to contact your social worker to get things moving in that direction.
