I guess you could start pouring a LOT of hot water down there but you may spend as much in Utility Costs as you would a plumber. They have equipment for this job.
At worst, find someone that's a plumber or has a friend that's a plumber to see what they say. Maybe they'll do some side work for a bit less than 'market value'.
My best to ya and hope this helps.
