That guy was insane

The estimate to take down the wallpaper border for the smallest bedroom in the house was $700 bucks! I think the guy must have had a screw loose. There is no way it should cost that much. We told him no thanks. I have decided to try and do it myself. I think I can get the border down but I am more worried about all the holes in the walls. I've never patched up a hole before and don't want it to look like a crappy job. We had heavy shelves up in his room which caused all the holes and also a large bulletin board. I guess that is another thing I will need to look up online. I know people patch up holes all the time but it's not something I've ever done. Maybe I will take pictures later to show the size of the holes.
