Hi,
I'm happy to chat with your brother, to help him work out what are some good questions to ask, when looking for the best kind of service provider / consultant is best for him. I might then either be able to help him myself, or I recommend someone from my network, or send a wider call on my linkedin profile for someone to help him.
