SYD to BNE, BNE to SYD transport - 12th to 14th December

Hi all,
I'll be doing a transport run from Sydney to Brisbane (and return) this weekend (12th-14th) with a car trailer.
I'd like to offset some of my fuel bill by offering transport of car/parts.
I'll be stopping at the following locations: Taree, Grafton, Yatala, but could stop else where along the highway.
On the trip from Sydney to Brisbane, the trailer will be empty, so I have space for a whole car or large parts like bonnets or engines.
On the trip from Brisbane to Sydney, the trailer will be full with my track car, however I will have space for small items if needed.

I plan to be on the road Friday 12th at 6PM so that is the deadline to have items loaded and ready to go.

Transport costs will be reasonable, it costs me $350 in petrol each way, so I'm not looking for $500 to transport a car :P (unless you want to pay that much :D).
