Oil leak that won’t go away.

Hi Guys: I think the rear main seal on my 74 Duster slant six is leaking. Does anyone know a good reputable knowledgeable mechanic in the Minneapolis MN area who could tackle a rear main seal replacement. He needs to know his way around a slant six. If he's an individual who might work out of his home or could commute to the job, I have a 6 foot deep mechanic's pit that the car is parked over for easy access to the bottom of the motor. Thanks!
