Absolutely, As much as you want to trust people you cant. I will never pay for a job until it is completed and completed properly. Its times like this it pays to develop a relationship with a mechanic and maintain it. My best mate owns a shop out at erina and is an absolute guru when it comes to engine building etc - When I mention how much people pay for "built motors" on this forum he almost has a heart attack. Some people charging close to 5k labor to bolt together a straight 6 is ludicrous. If only he would tune Ts (which is why im going to see the lads at c&v) but he is more of an old school and motec sort of a guy but will happily build an engine for anyone at alot better prices and with guarunteed better results than alot of 'engine builders' As an example when he built my xw motor and driveline he had just opened a new shop, no customers bar me and a few mates and he had no dramas getting me close to 15k in parts and wouldnt have asked for a cent till it was built and we had gone for a drive together to check everything is the way I wanted it. Drive the dodgies out of business, name and shame em if they want recourse they can sign up and voice there side of the story.
