Can a computer repair place fix this and can you estimate the cost?

Okay so if you want the details they are going to be down here.

I bought this computer off HP's website about 4 years ago, opening and closing it often caused the screw on the bottom side to create a hole where the housing for the charger plug in. So over time the laptop just had a weird little gap there that got bigger and bigger until now it just opens a lot and the housing is like hanging out because all the pieces on the side broke that hold it in.

It's still working but I know eventually if someone trips on the cord or something it will just tear right out.
