Neighbors Think They're Entitled To Our Property (sc)

My husband and I are having an issue with our neighbors who decided to cut down one of our large pine trees and several other trees that are on our property. We had an officer come out when the issue was first noticed and at the time, only half of the pine was cut down. We all agreed that he could continue to finish cutting, but only that one tree. We made it clear to the officer and our neighbor that we were getting a surveyor to come out because said neighbor pulled up the stake to show where our property ended.

Surveyor comes out and tells us that everything on the side the tree was cut was on our property, including a fence the neighbor put up. Also found the old stake which has been cut and buried.

We filed an incident with the police once again since we knew it was a civil dispute and wanted records. We then sent the neighbor a text and told them about the surveyor coming out and we needed them to move their stuff (building, fence, and other various items including trash) and we would allow 30 days. We also asked them to not do anymore with the tree.

They texted back that they wanted to speak in person, so we did. They tried to buy that part of our property, to which we said no, then tried to not move the fencing, to which we asked them to. We explained that we have 18 acres of land and the part they were trying to claim was left that way for logging trucks to come in and out to get to the back part of the land.

We had an arborist come out to tell us that pines aren't worth anything, but it would cost $1500 to get the tree and debris removal.

Are we able to take neighbor to court for the cost of removal by professional? We know they are not insured and the people he had scaling the tree did not know what they were doing (also noted by arborist). Or are we just SOL except for him getting his belongings off our property?
