Trakshak canvas & chip repairs before sale

I own a fantastic 2005 trakshak which faithfully followed us on a 10 month trip up through the centre and down the west coast and a 3 month trip up the east coast to Cape York.
I am about to put her up for sale but I need to get a couple of repairs done first. I don't have the tools or space to do this myself so I am looking for some help to find decent repairers in Melbourne (north or west is preferable)

I noticed on our last trip that there is a bit of mould starting on the ceiling, anyone know places that will fix this?

I would also like to get the stone chips on the front of the trailer repaired.

Any help would be appreciated.
