First off, sidemount is arguably not the best config for open water diving with no penetration.
Secondly, it sounds to me like the instructor doesnt have access to double tanks. SIngle tanks can be easily configured for SM, plus he may get a sale of a SM harness and charge you an extra $400 for the trouble!
Entry level tec classes are really important in shaping the kind of diver you will become. Just like golf pro's and flight instructors, its important to get a good one.
I would look elsewhere if I were you.
