No sorry @jimjazzuk , I used to write a bit of production music when I was in house at a corporate video production company a long time ago, but that's about it. I doubt that will be relevant to your query. I have a few friends who work in the field - I guess if it's a very general thing I might be able to help? but I imagine you might get more specific advice from the many folks on here who write library/production music full-time. Feel free to pm me if you like though.
