I sincerely apologize for my lack of conversion skills, but I am not sure how to convert your quilt size into inches and I don't know how to convert prices to American, but I do know that quilting prices in the US tend to be .01 to .04 per square inch. I would say you could expect to pay anywhere from $150 (very low end, very simple meander) to $350 (fancier design) for a King size quilt. There are a lot of people in the US that do long arming, so you would have a good choice of places to go. The cost of shipping the quilt may be cost prohibitive though.
Good luck!
