Rune Mechanic

I live near Frederick, MD. I am having trouble finding someone to work on my motorcycle. Does anyone know a motorcycle mechanic / diagnostic technician willing to work on a Rune in either MD, Southern PA, or Northern VA? My current problem is the oil pressure light keeps coming on, but it goes off when the engine is turned off and sits for a while. Trouble is it has been happening more and more frequently and I'm afraid I'll damage the engine if I continue to ride it. Unfortunately, the local Honda dealer refuses to work on motorcycles over 10 years old. Help!
