I'm not sure who is currently doing those sorts of repairs.
You might post the same inquiry on the Quad Line Kites Group on Facebook, lots of eyes there.
Sadly, this is a common issue with Revs, often occuring with less than 80 hours of fly time.
Just for reference, the Djinn has been in production for 3 years, over 1K kites shipped worldwide, and not ONE of them has reported any leading edge mesh failure.
