URGENT Requirement: Drupal 8/9 Migrate API MigratePlus YAML Expert

This is an urgent requirement and pays as such. If you can't do this within 4 hours, don't waste your time or mine, it shouldn't take more than one hour, it took me 1 hour to build the current configuration but I got stuck on the multi-value reference field part. I need someone who has created a large number of migrations, not someone who is only learning. I need to troubleshoot a very simple Drupal migration I created using the Drupal core Migrate API: [login to view URL] I have everything working, but I can't figure out how to handle a multi-value entity reference field that needs to perform a migration_lookup to find the referenced entities which were already migrated as part of a different migration. I just don't know Yaml very well, so most likely I am doing something wrong. See the attached file, it is the code I am currently working with. We have way more complex migrations but they use custom migrate processes and I don't want to make one for this migration but I am having trouble making it work without a custom process. Don't suggest custom processes, the API provides everything required already, I just don't understand them very well. We will need to work via screen-share editing the code on my local environment because the website requires a very complicated back-end environment. Although it is on Docker, it isn't easy to setup unless you're a dev-ops docker expert and I don't have time to walk you through setting up a local environment. The database is large and you need a lot of dependencies.
