You don't indicate where you live, but shoe build ups are of questionable value. An inshoe othotic is the most likely thing to benefit your child. Keep in mind this will not cure, the same as eye glasses do not cure and will need to be replaced as the child grows.
Birkenstock makes a good cork and leather orthotic with a deep heel cup. I don't know who you could send an imprint of the foot to. Perhaps there is a podiatrist near you who can help
