If the exclusive ownership of something, in order to sell it, is the primary choice driving factor of a project. Then you should just make it proprietary. Anything else would limit your margins, since someone else can just fork your project, change it and make it proprietary themselves. A dual license is sometimes used in this case as well.

You can sell GPL licensed software. You don’t have to publish the source code publicly online.
