Ask a location sound rental service. they most likely will have a Lockit from Ambient. It delivers WC, blackburst or tri-level. costs about 1000euro when you buy it so can´t be that much to rent.

make sure they have the latest version the older ones don´t do tri-level.

It´s normally used to sync cameras on shoots so you won´t find them in the post-studio scene. Rather ask production mixers if you know some. Those things are used every day on HD shoots.

here´s some info:
