3D Print Metal Radio Part

I need a very small metal part from a car duplicated using a 3D printer.

Requirements:
- Experience with 3D printing, especially with metal
- Ability to work from an existing part
- Low-detail replication is acceptable
Need to duplicate an obsolite car part. Need only one. Is cast aluminum and measures about 4" x 3" x 2"
Finishing is not important. Looking for a very reasonable price.
Couls send you a scan file, or the part for you to scan, or whatever you need.
