Well, there are probably "companies of questionable morality" that
will happily reverse-engineer a board and sell you lots of copies.
Strictly speaking, it may be easier to go photographically direct
from the existing boards to new boards without doing the useful
step of deriving the schematic.  After all, PCB manufacturing is a
photographic process.

Depending on the complexity and "strangeness" of the board, you can
probably use a combination of the traces, chips, and what you know
the circuit should look like to reverse engineer the board pretty
quickly; use a standard CAD package and a parts library that is set
up to correspond to physical reality, and see if the PCB you get looks
like the one you have.  Later, you can replace parts with more normal
schematic symbols.
