Taking Care of Business

We own one of the few largish plots of woods remaining in our area. Granny Tea owns another such plot, perhaps ten acres. There just aren't a lot of uncut woods around here.
A few years back a tree cutting business, let's call it "Orcson," contacted the relative who then owned our woods and asked to cut some trees. The relative told them no. They called back a few more times, and he continued to tell them no.
We moved out here and the Orcson contacted us and asked about cutting our trees. We said no. They called a couple more times, and we said no again.
Granny Tea moved out here, and the Orcsons contacted her and asked about cutting her trees. She said no. They said that if she didn't cut some of her trees, her woods would die, because it was a very unhealthy woods, and she needed them to save her trees by cutting many of them down. She said no, but she did call the DNR to ask them to advise her about her trees. He came out and told her the trees were in no danger and needn't be cut unless she wanted them cut. A farmer told Granny Tea that when they cut trees, they didn't clean up after the cutting, but left the tops of the trees around on the ground. They called Granny Tea again. She asked them about that. They said that of course they didn't take away the tree tops. They left them there as a favor, and she wanted the tree tops left behind because they provided habitat to the wildlife.
I told Granny Tea that the wildlife already had a habitat. We called it the woods.

The Orcsons called us again. By this time we'd picked out a site to build a house on the edge of our woods, and so, in a rash moment, we told them we'd sell them any of the trees we needed to cut to make room for the house. They came out, looked around, and vaguely said that they'd give us 2200 dollars for 18 trees. They said we didn't have anything especially valuable, but they could use those 18 trees.

We said we'd think about it. We had the builder mark the trees that would need to go, and then we called the Orcsons back and said, again, that we only wanted the trees cut that we needed moved for the house. Would they come back out and see if they wanted any the builder had marked? They hemmed and hawed, and scuffed their feet a bit, and said that it really wasn't worth their while unless we let them have two walnuts and two cherry trees that were in the log, and they weren't in the house portion. But they'd give us 1600 dollars for just those four trees.

We said no. To make a really long story only sort of long, after several more phone calls from the Orcsons, who continue to refuse to take no for an answer, the latest call was to tell us that they would give us 2200 dollars for those four trees.

To review:
The original offer was 2200 for 18 trees, trees which they said were of only general value.
Now we're hearing an offer of that same original price for only four trees, very specific trees.
There just are not many lots of uncut woods like ours still around this area, and ours is a pretty decent size. So wise tree cutters would realize that they are going to want to come back and do business with us again.
Questions:
Are they doing business as though they are thinking ahead and realzing that some day (perhaps very soon), they will want to do business with us again?

Or are they doing business with us as though they have never seen us before and will never see us again, so it doesn't matter how they present themselves?
