Pav.
He is a member here, (Pav79) as well as neptunestraps on instagram.
Very reasonable, at least a small fraction of what I see Jean Rousseau charging, and the quality of the work is excellent, imho.
He has done several custom style straps for me, I have been very pleased with them all
He sells some of his stuff here in SC when there is excess stock, look up one of his listings and see.
