Give it a go yourself. The only thing you MUST make sure you do not do is go down into the carbon during preparation. So when you are keying the surface up with sandpaper or whatever, be very, very careful to not hit the carbon.
Don't use Nitromorse, don't even think about shot blasting it.
Don't use etch primer.
I'd very gently dry sand it with 1200 grit, clean it off and then prime it.
