Looking for a shop near central PA to service Bafang motor on Dost Drop

[bobbymac5]

Hello. I have a three-year-old Dost Drop ebike with a Bafang BBSO2 motor. The motor is making a troublesome sound, but the company has gone out of business. Does anyone know of a shop or individual I could hire within a few hours of central Pennsylvania, USA, that could look at the Bafang for me? Thank you.
