I work with 2 people who meet those qualifications
They're both happy where they are and not looking to become a one man IT department like they seem to want, but they started as web developers in VB.Net, thus gaining IIS and some SQL experience. They are now DBAs, with even more SQL, Powershell, and server administration experience. I just want to point out that while candidates that meet these qualifications may be rare, they do exist.
