Any place where I can machine or make a small gear from a 3d file

I have a 3D stl file for a gear I require for a DIY project. I was looking for a place that will CNC machine it for me using the 3d file. 3D printing is not an option since all the places in Qatar only print using PLA material which cannot withstand high temperatures. So looking for a way to make in metal.

Or if anyone knows a place that can 3D print using nylon material (high temp resistance) , please let me know.
