Actually if it were me, I'd take the deal. About 10 years ago I passed on a 31 roadster body, less the floor, that was for sale for $850. I wasn't sure at the time if I wanted to invest that much time in building (and rebuilding) a roadster. Kicked myself many times since. Couldn't even buy fenders for that price let alone the a body including the windshield posts and a rumble seat. Took me a long time to get over that mistake (at least I think I'm over it )

Looks to me like you getting most of the really important parts, so even with out a huge infusion of money, you should be able to make good progress on getting it to the road.
