I've used Anodizers Pty Ltd in Barry Ave, Mortdale a number of times and have found them to do a great job.

The poles on your Lightbridge would already have some kind of coating on them, so this would have to be cleaned off first, which may or may not be possible. Best to take them over and let them have a look at them.
