Upgrade Current Raspberry pi running Icecast to have SSL certificate.

I have a raspberry pi running Ice Cast server streaming Live Feeds. Its current address is [login to view URL] I need it to have an SSL certifcate that will automatically update and the port to stay the same. In the end the URL will be [login to view URL] The easist way possible Ill pay small monthly fee if its required. I have 8 pies running so I would need this done 8 times or I can pay you to teach me so I can reproduce what you did. If the certificate need to be manually update I would need insturctions to do that.
