Is this an original MBA or a new/revised MBA?
If original, I would suggest you take it apart and try to fix it and bend it back in place yourself. They are so cheap to buy that paying a small fortune doesn't make sense... costs around $900 in the US just to replace the lid with display. Refurbished original is $999.
Now, if it is a rev B or Nvidia MBA, I would advise you fix it, and sell the broken part on eBay. A lot of people have broken hinges, and that may give them the hinges... NOT anywhere near 100% sure, but seems like someone could make use of it. Plus, those that have bad display could use the display and swap out. I know with MBP that I had, I could take all apart, so I am going on that. Seems like you could sell the hinges for a nice sum and the display for a pretty penny too.
I also have seen aluminum replacement parts on eBay, if you could just replace the aluminum lid, and use your display, that would work.
Wherever you get it fixed, make sure you get the original parts back and sell them online, as seem super valuable.
Good luck.
