will I be able to fix my LG Cosmos 3 for a cheap price?

I was sitting on my couch and my phone slipped out underneath the cushion with out me knowing. A few days later I found it and I noticed that there was something wrong with it. When I slid it open to text, it didn't feel right. It was loose and wiggly. When I opened it again I noticed how the top part of the phone was broken of the hinge that allows the phone to slide. Now only half of the top part of the phone is connected to the hinge. I have a 2 year contract for the phone and I didn't want to half to pay a lot of money to start a new contract and get a new phone. I also didn't want to loose all my pictures and other things from this phone. That is why I was hoping that you could fix my phone for a cheap price. I really hope you could please help me out. Thank you.
