Welcome to KCA Shep.
I can't recommend anyone up that way as I don't have experience with the workshops in that region......
I would say, though, that panel and paintwork is expensive if done correctly as it is very labour intensive and time is money.
Don't be blinded by what looks like a nice ,shiny paint job. The prep. is more important than the finish.
Poor prep. = rusty tears and more $$ down the track.
Ask for photo's of any rust removal / repairs from previous clients.....as well as referrals.
Go and see the Workshop yourself. A well organised Workshop is a good indicator of the capabilities of the Owner, in my opinion.
(Having said that, I also know of a place that look like an absolute 5hitfight.....but turns out good work.
)
Do your research well and don't jump in too quickly....once a place has your vehicle, you are at their mercy.
Good luck
