Your car is beautiful , but I think 10-11k is good money for it. Its not really drop dead gotta have it (imo). Nothing in the car is overboard except the exterior. the 2v swap is nice but the AC in the trunk is a bit off. I would have just sold the car, most people sell there build up notches with dart blocks, turbos, t56's, and all the trimmings from 14-18 and they cost 30-40 to build.
Hopefully you will find that one guy that has to have it and you get what you want but if not you could always trade it for something easier to sell.
You didn't mention whether or not your 30-40k estimates are labor inclusive, or all based on cost of hardware alone.
Even at $30.00 per hour, if I had to pay some body shop to do the body work on my car, it'd be 30k w/o one piece of hardware. I don't know of any bodyshop even doing custom bodywork for 30.00 per hour, do you? ( or ANY bodywork for $30.00 per hour for that matter)
I realize that the end result of that bodywork isn't for everybody,.....but it doesn't take a trained eye to know that there is a bazillion hours in the labor to get it there.
The parts,.....now there is a different story. We all try and forget the "investment" we've put into these cars to get them to the perfect stage, ( and for the sake of my marraige I try to forget,.....conveniently) but if I remember correctly.......OH hell let's just look shall we?

This doesn't take into consideration the goofy assed homemade K member, subframe connectors, crossmember, or the fact that I payed that painter through traded out labor,....most of these "guesses" are low, and I'm sure I've forgotten some stuff,...
But I certainly have just as much in my car as your Dart block based/turbo build cars you cited.
Not that it matters anyway,....I'm not selling it anymore anyway. I'm keeping it for the rest of the year at least.
