How do i make this part??

Any shop with a good CNC Lathe can turn that out in no-time. The holes around the perimeter are also trivial on even an NC Mill. The trick is the tools you use to build it. You should be able to use Google to find a machine shop in your area that can quote the part (A really good shop will ask for the 3D files to make the part). Who knows - you might even find a new sponsor for your team this way!

Good luck!

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.
