Tree disposal

I have 12 evergreen trees in my backyard lining the fence They were there when we moved in, in 2021. I assume they were there to act as a fence, before the previous owners put up an actual fence.

Anyway, they're getting bigger and are taking up way too much space in my back yard. I want to cut them down but I don't know what I can do with them once I cut them down. Can I bring them to the dump? Will I have to pay a tree service to chip them up?

Need a little advice.
