One snag is that I doubt you could ring up an agency and ask for half a
dozen Haskell programmers. You could probably get people who did a bit
of functional programming as part of a computer science degree, but that
may not be enough for your needs. (Having said that, if you did manage
to find contract Haskell programmers, you would probably get people who
were highly skilled, and enthusiastic about the chance to use the language.)
In other words, Haskell might be a good answer technically, but it could
paint the client into a corner business-wise.
I currently have a small amount of business logic that is implemented in
Haskell, and I want to see it increase, but I'm always worried that this
is going to happen. I don't want a job for life maintaining this stuff,
I want to delegate it to others at an appropriate time.

You might find that Java, for example, would have more support for this
type of application, out of the box. Although Java is an unimaginative
language, I find that productivity isn't too bad, mainly because there
is plenty of library support for typical applications. With Haskell,
writing the business logic is quicker, but some of the time saved gets
spent implementing things that come as standard with Java.

I'm finding this quite a struggle, to be honest. I can cope easily with
the various homework assignments that get posted here, but I find it
hard thinking about large applications in functional terms. I'm
building up to larger applications, but I'd feel nervous tackling
something the size you are talking about at the moment.
