I would go buy a cert.

They aren't much money and you can specify the granularity you want  
the cert to have, the more granularity, the higher the cost but they  
are not that much anyways.

Wether your site in internal or not is irrelevant as you should  
approach your LAN as a hostile place.

After all, 75% of breaches occur form within.  You can take that how  
ever you want but the days of a soft nougatine LAN are over.
