To the OP, couple thoughts
First, you've answered your question in the original post. You stated, "I'm outta my league on this one and I don't want to end up winning a Darwin Award". This leaves either a pro climber or arborist with a bucket truck as the best recourse. svk gave you some great advice in getting quotes from an insured company(s) to just put it on the ground and leave the clean-up. On a tree that large, there will be a lot of brush, chipping, raking and blowing, etc. If that clean up is not in the quote, I'm estimating the time of the job just went from 1 to 1-1/2 days to probably a 1/2 day or a little more depending on set up and access. I'm also assuming a crane is not required.
My other thought, from experience in dealing with trees this big over the years, both felling and helping my arborist buddy, is quite simply well over half of the trees, regardless of species, when they reach that diameter are no longer solid through and through. They resemble for lack of a better term jelly donuts. This means whatever you planned on for holding and hinging wood to direct the fall may be no more than a huge mass of core rot with the consistency and strength of oatmeal. Use of ropes, cables, and winches will add some amount of predictability as to fall direction, however once the stresses induced take over and the trunk cracks or indeed starts to roll, that tree is going where it nature and gravity take it regardless of what's in its path.
Wishing you a favorable outcome.
