SSL Certificate from a Trusted Certificate Authority

Hello,

I have deployed a Desktop Hosting Service on Windows Azure using the following Microsoft Deployment Guide which works well using self signed certificates:

I now wish to install a certificate from a trusted certificate authority instead of self signed certificates. Is there a deployment guide I can follow to do this ?

Thanks
