[ Instead of writing back in text, it's a far more logical route to simply communicate in a preferred method, signing back with incredibly practiced hands.

Hello Regan. My name is Connor. I'm sorry there aren't more people familiar with your communication method. I've been told I'm not the best conversationalist but I'd be happy to chat.

There is a university here. Perhaps you could combine teaching people the language and employment by holding a class for sign language. There would be no age-restriction or prior employment experience necessary for teaching something you are an expert in.
