I would suggest posting a target price, before people spend a lot of time working a quote. This is an unbiased opinion from someone not interested in bidding the job. If you want a cosmetically nice, in tolerance part, I think your looking at a lot more money than you would expect, if you are not familiar with manufacturing costs. This is one of those parts that would have a small per unit cost if cast in volume, but machining 1-3 is going to be expensive as programming and set-up charges are amortized over so few units.
