Does anybody know if he's still in business?...

http://www.thexmancustoms.com

I sent a message requesting his service as his website instructs, but no response...

Or is there someone else I should use?...

Thanks in advance!

Let me ask, I know a few people who talk to him personally.

That was the URL sent to me just now, so perhaps he's busy. The person I talked to also said that you need to fill in the PDF form for any submissions.

yep, I filled out his form on his site...

I'm looking to get a nose bridge tune up on my Juliets...

I just filled out his request form again... any confirmation he's still doing this?

Yes, he should still be operating.
Try sending to his e-mail on his Order page rather than the form.

He got a hold of me today... all is right in the world once again

YEP,
I'm still doing tuneups,i receive a lot of e-mails on a daily basis so im sorry if yours was overlooked.
