Help make my garden safe for me and my guide dog

my original garden layout was not safe for me to go outside and get up onto my grass and the rest of my garden as I am blind. I paid for somebody to come and install decking, a new fence to stop my guide dog escaping and for my patio section to be levelled. Unfortunately it was not done correctly and now has to be rebuilt.I paid out a lot of money in the first instance and the original person will not come back and fix it… I would be grateful for any donations possible to help make my garden safe and a nice place for me to go outside and play with my guide dog. If once I’ve had all the work done I have any money left this will be donated to Guide Dogs for the Blind

 (I’ve had to increase the amount because of the fees the website takes)
