This is a fairly close going rate for jobs:
TST plate installed, 250$
3k govs installed, 250$
timing 200$
KDP fix using the jig, 200$
KDP tab would cost more due to more materials and more time... 350$?
250$ installed doesnt sound bad at all for 3 gauges though.
But for 1400$ Id expect at least a plate, gov springs, timing, KDP fix and gauges, all installed... considering thats only ~550$ in parts, max.
Just MHO though...
