Hi, I know that this is an old thread but I thought I'd reply anyway. Bill Goodyear has moved to Cornwall, but he still coaches adults with Aperger's, by phone and comes up to London regularly to meet the people he coaches.
He's just about to start coaching my son, paid for (hopefully) by our Adults with disabilities team at our Local Authority.
You can find him on facebook or twitter

He has also written a book
