Python3/Flask/SqlAlchemy/Celery starter proof-of-concept

hi guys, I'm looking for a flask starter that shows all of these working in the right way. I have a legacy flask app that is a complete mess and I would like to see how to do it in the right way. I see a lot of code on how to write an application - but very very little info on how to build a production ready system with all the nuts and pieces needed to make a great production ready system.

* gevent + gunicorn + docker - get the flask app to work in production in the best way possible. How do you setup monkeypatching, etc ? Remember that sqlalchemy is also in this mix. And a huge pain is loading config files - staging and production. We will use Docker - so you should demonstrate Docker instances with production and staging environments.
* sqlalchemy/postgres - autocommit or not ? autoflush or not ? How do you write a model in the way that you dont have to do this for every function you write (and you can do this once in the base model or decorator or something). This is a huge, huge PITA for me
* celery/rq - how do you run celery/rq and workers using docker ? One of the biggest questions for us is how to load the same sqlalchemy models (from the main flask app) into the celery workers. We invariably end up loading flask code as well. Also needed is how to handle errors in celery - we want it to go to a failure queue.
* msgpack - we want to return msgpack OR json data based on what the client has requested for. The api should also accept incoming msgpack OR json data. Obviously we dont want to write this code inside each and every function/endpoint. We would prefer doing this in a decorator. write a decorator that lets you return an object (e.g. a dictionary) from your request handler, which the decorator then serialises to either JSON or msgpack depending on upon the Accept header.
* Blueprints - load blueprints in the right way.

I'm looking for a starter template demonstrating these features. And I can run from there. P.S. I'm actually willing to pay for this - not sure if it is kosher mentioning that here. But I'm happy to have someone take the time to do this and make it opensource for the community.
