How do i make this part??

I would agree that local is typically a better connection.

If that's not an option, what I meant by my word of caution is that not all shops have same quality or service. I didn't have any real problems with the 4 companies I worked with.

MFGquote will get you a good number of quotes (from around the world) in a day or two and they will have a huge range (just a guess $50 - $800) and you'll just need to look up the suppliers rating on the site. It's just like buying anything else online, sometimes the cheapest will only get you a bad product (and sometimes the most expensive will). Look at local or regional bids and to keep the cost reasonable correctly dimension your drawing with reasonable tolerances.
