You can try North Sails in downtown.I walk in there last year with kite in hand and ask as politely as possible if they can fix my kite,sure made them know that Im not in rush.,kite was clean as possible.Got it back after week or so.
one of the best in industryhttp://www.windfiredesigns.com/repairs.html
You can take pictures and ask for quote in advance.They will send you bill after you receive kite back and all looks good to you.I send them lots of friends and everyone was super happy.They always done amazing job,take a look around their web.
note,I have no tie to them,just putting up what did work great for me in past. +they were incredibly inexpensive.
fyi,.Jens watched me to do similar thing in South Haven on my bday.Very first wave on the day,sooo overpowered on 9m,lost balance on top turn and tried to save myself with kiteloop,not enough time to finish the look,tomahawk
