Just do it yourself. I had the same thing with our X3 and it was easy to replace. Off the top of me head (for our X3 at least) there were only 3/4 screws to remove. It would have been a five minute job tops but I dropped one of the screws which took me about half an hour to recover. Make sure you've got a decent magnetic screwdriver or one of those extendable magnetic wand things and you'll do fine.
