No matter how complicated the plane, the buyer wants it NOW. Don't kill your hobby by putting pressure on it.
I know that would happen. That is why I would be very reluctant to take specific projects, because I am slow with the time I have available. I was thinking more along the lines of building popular kits on spec and then selling them when I finished, to whoever wanted it. Sounds like that is not a reasonable option at the moment.
