Disclaimer / shameless plug: I have an OSS project in this space, https://www.reactivated.io, and plan to do a Show HN on it tomorrow.

With that out of the way, I think having more opinionated Django frameworks is a great thing. Particularly around styling and forms.

I also think it's interesting to try to "productize" (I think there's a better word) what is often done as consulting. That is, bottling up and selling experience. So while the price may seem high, there's a ton of wisdom behind it. An experienced Django consultant is easily thousands of dollars per week.

I wish you the best!
