I tried to take a look. Last time I checked it was $42,000 or so if you picked them up. Now you have to request a price. Since I am happy with my wings, I won't bother them, but if some forumite does, please let us know?
On the "shop" doing these things, 300 hours at $100/hr is only $30 grand. You would be lucky to find someone to bring a Cub or Champ up to snuff with new cover for that. We are hobbyists. The rational choice - buy already restored, or do it yourself.
There is a third option - be incredibly wealthy and hire a buyer.
Also -Legend Cub in Texas does really good restorations on Cubs, and Steve Pierce in Graham Tx has a fabric department. Steve is a good guy, and may be able to advise you. He too does mostly Cubs, but there are more similarities than differences.
