I sail a bit everywhere. Unfortuantely probably don't have the time really, moving house over the holiday period.
But as stated above, board crazy I think sends boards off for repairs.. as does goodtime.
p.s. what did you do too it? if its just a little dent not hard to fix yourself :)
It's really not that difficult to do yourself, and there are some great websites to help. Failing that, there's plenty of people here on Seabreeze willing to offer advice along the way.
It won't be the last time you damage your board, so money spent on materials is worth it long term, and you dont have to wait for someone else to do it. Back on the water sooner. Search board repair in the forums, theres heaps of info.

The ding shop at Mermaid Beach on the Gold Coast. I have only heard very good things about the work they do, and I have seen some pretty impressive repairs they have done to epoxy Stand Up Paddle boards.
