I seriously recommend checking out the studios Perverstage and Seductive Studios. Seductive Studios has a tickling-dedicated patreon that I always love recommending to people. TickleBabes.
When it comes to producers, I've had some awesome experiences with Constance https://constancescrazycinemas.com, and Hannah Perez https://hannahperez.net. Hannah herself sadly at this point doesn't appear on camera much anymore. But she works with really great models.
