I second this. Code without people expertly familiar with it is a liability and a risk, with unbounded/unknown associated long-term cost of training, further development if possible, or a rewrite (in which case starting from scratch anyway), and maintenance. ..Then perhaps it can be recommended for the OP to "sell" the code together with the expertise/team/himself as a package? If I were in a situation where my company needed a solution that he describes, I might be interested in such a package: fully functioning software with a domain expert (who has proven able to put together and lead a team).
