I've raised £3000 to install a special swing for Tom, aged 19, who has autism, severe learning difficulties and epilepsy

Our gorgeous son Tom is now 19 and moving into adult residential care. He has autism, severe learning difficulties and epilepsy. These conditions mean he needs round the clock care for life.
His new home is a great place but it doesn’t have a swing, and Tom LOVES to swing. He needs several hours of swinging daily to keep him calm and physically fit. This helps keep his seizures at bay too. The Local Authority will fund his home but will not pay for a swing, so that is down to us to raise the funds. Tom is a strapping 6 foot lad so way too big for the sort of swings sold at Argos! He needs playground grade heavy duty play equpment, properly installed.
Please help if you possibly can. We have had several quotes around £2500.
Tom says thank you.
