Financial entitlements for children with SEND- 1-2 page guide

Description

I am looking for someone who is knowledgeable about financial entitlements for children with SEND.
I run a Charity, 2 social enterprises and a business. Some of the work we do is free, but others at the moment we can only offer to schools or people paying privately.
I have been told there is money available, but not enough providers to spend it on, for things like direct payments and respite.
I need someone who already knows a lot about this, but is willing to ring up support organisations to clarify if needed. Who can put together a 1-2 page guide on the types of financial support for families of children with SEND, who may be eligible and how they can be used.
I have a few different activities that parents have asked for help with funding for, so you would need to also check to see whether its possible to use these for direct payments and how to do this
