Question : Building a Composer / Music Supervisor Network

Hello Score it Community, I am a long time film and television professional and have recently returned to my composer and music supervisor roots. You would think that being in the, albeit non-musically side of the business, the bridge to other side would be fairly easy. Sadly the industry loves to pigeon hole which has persuaded me to start from scratch although this is not necessarily a bad thing. Does anyone have any suggestions about the best way to build a growing composer / music supervisor network? Clearly, from what I have seen already, Score it is a good start.
