[Looking4] Precision faceting in Thailand

Might anyone know of a company (or companies) who will perform
precision (or near precision) re-faceting on old jamb peg cut stones
in Thailand.

I’ll be in Thailand next year for several months and I’d like to
start a relationship with a company where I get 20-100 stones cut a
month, most are medium quality “fat bellied” spinels, tourmalines,
zircons, etc, which were cut in the '40’s to 60’s, probably in India
or Thailand.

Names, addresses, telephone numbers, ect would be appreciated.

Does anyone have any experience doing this? Especially taking stones
from the US to Thailand, having them re-cut, and then repatriating
them back to the US.
