PA needed for 7 year old with autism.

We are a family of 3. 
Single mum with 7 year old son and 4 year old daughter. 
Both children have a diagnosis of autism. 
We have been allocated hours for both. 4 year old currently being supported however am looking for support for my 7 year old. 

B is entitled to 4 hours a week direct payments. 

B communicates using a variety of methods. Some Makaton, some but muffled spoken word, typed words and through a communication device. B's strengths are his knowledge of logos, and able to operate technology. Amazing at maths. B struggles with social communication, loud environments and attention. 
B would benefit from being supported to foster his independence skills. B enjoys time out in coffee shops and shops. He isn't a child that enjoys soft plays, parks (unless there's a sandpit). B loves all things logo, (tv channels, cars, food places). B is a very chilled child however can find social situations overwhelming at times, his anxieties can rise and lead to fleeing. 

Please feel free to message me with any other questions:)
