thats good advice. There are a few portable mill guys around here. Put it this way, I have mature hemlock that is probably 40" plus in diameter and the pine is close to that or more as well. Never thought about the sawing of it though, although the pulp prices here are decent
Don't pulp the pine... especially if red or white pine... especially if as big as you say they are... especially if they are straight. Big, straight pine is in high demand by Scandanavian scribe-fit log home builders and smaller diameter, but straight are very marketable for utility poles if such a buyer is within a couple hundred miles of you. No matter how decent the pulp prices are there is no way they'll be the price for sawlogs. As someone else said, you may have rot, disease, etc. being as big as they are. However, only you know your trees and if this is the case or not as they stand on your lot. With that said though, I've milled white pine and other species that have been quite large only to get a few good boards from the outer wood and find rot in the middle of the log. Quite often aspen will end up the same... looks like a nice, straight, healthy tree standing on the stump but find that its rotten in the middle once you knock it down and mill into it. I've also had both aspen and pine snap in two as they hit the ground if their middles have been rotted out... again, nice looking trees, but rotten in the middle. The hemlock will likely be less valuable as it is not generally a species that is highly sought after. However, it can make good fence posts since it is quite dense. If you have the hemlock sawn into boards you generally would use it green since when dry it is nearly impossible to hammer through... although you can also drill pilot holes. Another think to consider would be to leave the hemlock grow. Hemlock can grow to 600+ years old and is an excellent wildlife habitat tree given its canopy cover and shelter characteristics. Wildlife habitat is another aspect of your property that you may want to consider in the overall management scheme. Lastly, you don't have to harvest all trees at once. In your situation, I'd look at harvesting poor quality trees first to open up the healthier trees to more sunlight and water... again, money in the bank. Then, look at harvesting the good mature trees as they near the end of their productive life or as they die off.
Don't just take my word for it thought. There's a lot to managing a forest properly and a lot of different techniques to consider based upon your wants and needs. I would start by ordering a copy of Full Vigor Forestry as mentioned previously. You could also probably get some free forestry assistance from your local conservation district if they have a forester on staff.
Regardless, look at beginning to start some management regimes this summer to grow your investment... it sounds like a valuable piece of property both ecologically and financially. Managing it properly will make it that much more valuable, but it will take 10's of years to compound its value as trees and the property they grow upon are a longterm investment.
