Answer 1

You may have to check local official authorized Apple service providers for a price or estimate on the cost of repair parts and labor; there may be other companies than those officially listed in the locator page here http://www.apple.com/sg/service/ in the Singapore area, that can do the job. Be wary of those not Authorized or Certified, since these may not use the correct parts or may not be properly trained in the repair procedure.
In the case of a computer still under offiical original or extended Apple warranty, when accidental damages cause need for a repair, be sure to get the damage fixed in an authorized repair facility so as to keep the remainder of the offiical warranty in effect. Unofficial repairs by unqualified persons can void the remainder of a factory warranty; while the damage may not be covered at all, the rest of the computer could retain coverage if it is repaired correctly using Apple trained and authorized service personnel and original equipment parts.
So, be sure if you find a shop that can do a repair, that it won't make matters worse by performing inexact or  sub-par service; and if the computer no longer has an official warranty on the remainder of the unit (outside of the accidental damages not covered anyway) you may be able to find a good display, new or used, and have another service company replace the one in your MB/Air. Depending on what build year-model MB/Air 11" you have, the parts may vary; so be sure to research whoever can do this job, so it may be done correctly. 
There are independent authorized Apple repair agents with certified technicians who use correct parts, so maybe you can find one in your region; at least to initially research the costs involved in restoring the MB/Air.
Not sure which model you have, but for something out of warranty or damaged in a way to no longer be covered, you may see what may be involved in doing a repair or parts swap, yourself; the following may be helpful in restoring this model.Or give you an idea, should it be too technical for a DIY fix.
