If you take your car to SEI motors, i would only recomment 1 mechanic from that place. I can give you his number if you PM me and he does it privately for much cheaper than SEI motors charge. His name is (Removed - PM me for name) and he also previously was prepering cars for bathurst and was also a driver of an R31 in tagra races in the day. If your nice he will show you some video's of him driving in the races He only charges by the hour + parts. I bought my car from SEI motors too, was the best car on the lot. They dont have much to choose from at all.
