Spending twice as much on machine work from a machinist that gets it will save you 10 times as much later. If you can't afford Bostick or equivalent, buy a used motor to hold you over until you can. If you decide to go with someone else, get in touch with me or ?? And I'll explain what you need to watch out for, spec, and check for when the job is done. Most automotive machine shops do shit for work....but they make it shiney and pretty so you don't ask questions
