Depending on how long it has been dead and just hjow sound the dead wood still is. I had some pine trees that were dead and were unclimable. I got estimates from several companies to just get them on the ground, I would cut up and dispose of the wood. Also had a price on remvoing a huge oak by my barn. They wanted 1,500 to cut and drop my oak as 90% of it was over my barn, and they wanted 750 per pine plus crane rental and trasnport charges. I have used a chain saw most of my life but these were hazzard trees (the pines were the oak was not) and I was leary. I enrolled in a arborist school of 6 weeks duration and also took a tree climbing course of 2 weeks. Got finished with them,. came back and had both pines on the ground safely and just trimed back the oak. That was over 10 years ago. I placed lines in good pine trees and made a suspension lne that went by the dead pines, went out on the suspension line, and worked the pines to the ground while hanging from the suspension line. I used proper rigging and ropes and gear, and even after buying all my gear and supplies, and the cost of the courses, I still saved close to 500 in my pocket that other wise would have been up a hogs butt and that was not counting what a crane rental would have been which is somewhere in the area of 200 per hour with a min of 4 hours. I learned the proper way, and also made a fair amount of money on the side doing removals etc. Its amazing what some folks charge for jobs like your pine. Some may be brazen enough to monkey their way up and taike it down piece by piece others may just amble under it and drop it all in once piece and another may hire a crane, fully sure of themselves that they will be home for supper that night after work unlike the others. Whoever you get, make sure they are bonded or insured and ask for references. They won't have any reservations on providing you what you ask of them if they have integrity and do a good job. Accidents do happen, so a bond or insurance is a must on their part.
If you see a Asplundt or Davey Tree Service truck in your area, stop and ask if any of them do work on the side. Lots of times its not unusual for the same crew to use the company equipment and do side jobs. Their company insurance probably would not cover damages though.
