Postgres-Sequelize Model and Migration Files Needed

I have experience with relational databases, but I'm new to Sequelize and am having trouble figuring out where I'm going wrong with setting up associations. I've created a simplified data model, and I'd like someone to help me by creating sequelize-cli migration files for each database object, the Sequelize model files that correctly reflect the associations between each model/object, and then some tests I can run that demonstrate a couple of Sequelize "magic methods" for each association so I that I can confirm they work, and also see how they work since I haven't had any luck with Sequelize associations to this point.

I'm hoping this can be turned around quickly because I have the full model otherwise working in my application, and I hope to continue development very soon, it's just the associations I'm having problems with, so I'm looking forward to seeing what I'm doing wrong. The details of the objects needed and the facts about the associates are in the attached.
