I'm helping develop a new television drama for HBO that will be filmed in early 2018. The story focuses on young bankers and their relationships, but there is a BDSM thread that we are trying to perfect. We don't want to misrepresent this world, so I'm looking for advice from active members and experts. The show's writers are currently in session in London, and will be for the next four weeks. We're looking for useful and interesting contributors to come in for an hour or so, but we're also happy to interview people over Skype. Please let me know if you can point me in the right direction.
