How much does it cost to fix a broken laptop screen border/hinge?

I have a Dell Inspiron 1545 laptop. About a year ago, I broke the hinge on the screen and haven't gotten it fixed. It's gotten worse, as now the outline of the screen is cracked and the whole right side of the screen is disconnected from the rest of the laptop. The screen itself is perfectly fine. I don't have a warranty. How much would it cost to have Dell repair this, about?
