I don't think that's possible.  If I understand the problem, the
moire effect is intensive, global noise with continuous variation in
scale and contrast, resulting from superimposing a slightly out of
alignment shadow or reflection on the image content.  I don't think
any filter is likely likely to be able to distinguish that kind of
noise from image content - without a perfect copy for comparison,
which of course ain't relevant here.

Hopefully the folks who failed on the first try will succeed on the
second, otherwise, I would try someone else.  They should have kept
trying to fix it and/or admitted to failure, instead of delivering
useless junk as finished work.
