That's fine, except don't call it an "open source" license. That's a commercial license.

I think it's still open source, it's just not free right?

The Open Source Definition precludes that type of license, since it discriminates against Persons or Groups or Fields of Endeavor:

You can of course create such a license, but it would not be an open source license, more like a shared source license or ethical license or something else.
