Hadn't seen this post before, but I believe you make the right decision. I was in a similair position six years ago when I decided to create the Ordo Quaesitoris, and after three long years, I can say that you can't really create a full corporation, and a succesful one, without involving yourself knee deep into it, and giving it all the time you have. As soon as it disapears, or is reduced, either you have grown enough to have a decent size (and it is growing a lot, actually!), or it will start showing your lack of guidance and, eventually, vanishing.
At least, that's my experience on the issue, and the main reason I don't bring the OQ back is because I don't have the time to re-create that niche position.
