Hi @GOD_Rocks , adding up to @AlyssaPandora's suggestions.
What I have done before is ask musician friends to see if they know someone and go music shops. It may be a more outdated method but, for me, it has been effective.
Many music professors go to the shops and may leave their contact there in case someone goes looking. Also since they may need to go relatively frequently for chords, musical sheet books, or supplies they may have their contacts too. This works specially well for small and local shops.
Hope this helps and good luck! 🍀
