Need help with airbag fixing

Please help. I was hit by an uninsured driver and having to pay out of pocket to fix my car. I am student so this is really pricey for me.

 

I need to replace my driver Airbag in the steering wheel and my front two seatbelts too since they are stuck. I don't boeve that my Clockspring needs to be replaced since eeverything is working. Everything else is fine. My horn works, turn signals work, the car drives like before. 

 

Where can I get parts for cheap and get it fixed for cheap as well?
