Tree Trimming

Good morning. Three in front of my house has caused major buckle in the sidewalk. City put asphalt to help tripping hazard, but its still unsightly and the tree is not in great shape. Its not too big a tree, and I would like to cut it down, repair the sidewalk and replace it with a new tree. I would be happy to have this done at my expense if the City cannot do it. It needs to be repaired. Thank you.
