Financial help for an autistic child

Hello,

My son has been diagnosed with ASD and my question is about financial fund for him as I know that some organisations offer one. Is it possible to apply for funds that could be spent abroad? I found a recreation and recreation centre that provide therapies for autistic children but the cost of the batch is very high. We could provide authorities with all necessary receipts to prove the expenditures. I wonder if it is possible at all. I would be grateful for any responses. 

Many thanks!
