Help my son has autism and I need to get him a high school place

Hi my 10 year old son has recently been diagnosed with Autism. I have been home schooling for the last year due to him being bullied in the school he was in. ( some off the kids were kicking him in the privates, punching him in the face on a daily bases becouse they had said sorry after doing it he always classed it as a accident)  anyway  due to him only recently  being diagnosed I am finding it near on impossible to get a SEN report for a suitable school for him. He wouldn't be able to go to a mainstream as he is easily lead  and does not realise when people are being nasty or taking the Mick and he has no sense of danger!
