"For instance I recently joined a project that was built by devs coming up to speed on React. And boy did they abuse Flux, they didn't build a store for every drop-down but it's pretty damn close. However I really think a React Guru could have steered them around this mistake with just 30 minutes of his time.

The trouble here is that the guru or consultant who comes in needs to understand the context of the problem, which can't be done in 30 mins.
we have a lot of architecture consultant companies which provide these services already.
Am I doing anything wrong isn't happening in 30 mins. Am I doing anything wrong with React is more than 30 mins. Am I abusing Flux? That sounds doable. videoconference with a live dev plus codebase access.
In a previous career I walked hundreds of consultants thru connecting to the telco WAN and ISP network that employed me, and I can't help you with everything but in 30 minutes I can easily tell you what is wrong with your BGP configuration or your frame relay configuration or your MPLS/ATM connection. At least WRT connecting to that employer, at least WRT connecting 15 years ago. The consultants knew their client networks inside and out, I mostly told them "no do not redistribute via RIP RFC1918 address space to us" or "no you really don't want to send us a 0/0 route" or "you think we'll accept a route for a.b.c.d/27 and you're actually sending it correctly but you not having sent us a LOA means I'm filtering it right out" or "you might want to think about enabling md5 authentication because we have, as our welcome letter you obviously didn't read, clearly explained" and yeah people actually tried stuff like that. Also people with obvious peculiar ideas about how BGP works WRT priority of routes and load balancing and stuff. Could I tell these "network administrator consultants" how to set up MCSE server stuff, well, no, but I sure told a lot of them how to configure Cisco WAN interfaces and how BGP works (or doesn't work)...
You can do a lot in 30 minutes over a narrow enough specialty.
