Standing dead timber is good for wildlife. Standing dead timber next to your house or dock is not good for obvious reasons.
One thing that may or may not help you but would certainly be worth a shot, is contacting the Belknap County Extension office. I have used them before and they are very helpful. The county forester for Belknap is Andy Fast, I have his email if you want it and I will pm it to you.
They can certainly give you some good ideas as to your options.
If the trees are tall and straight with no branches for a while then they could actually be worth some money. Certainly not 1200 per tree but maybe enough to offset some of the cost. People talk about only hardwood being worth money but that is not true, there are a lot of local sawmills that buy nice pine logs for many uses. Timber Framing is big in the northeast and it can be hard to find long straight knot free logs. If they are really 80-100 tall then you could be throwing away a lot of money!
For example, I just milled a 16' 8x12 and multiple 16' long 2x boards from one single log. The 8x12 alone would be just over $100 to buy.
