Would also like to know how much he charges anyone know?
OK, I got in touch with him. His name is Gewirtzman, and his cell phone number is [ETA: Redacted. Please PM for his number]. Charges $20, takes him around 10 min while you wait in his house in Coventry, usually does bein hasedorim or nights, call to find a good time.
I will report my experience after I use him.
