This field offers incredible opportunities for growth and learning, and it's great that you're eager to master it.

I have had turns where things are recommended to repair based on the field operator and my property managers notes, and I would expect the professionals with eyes on the property to have the best opinion on when the inevitable concern arises. 

I was thinking I would create a course that involves a field trip to one of the flips I am working and pointing out all of the things they should catch and helping them understand rehab costs at a line item level.I am an expert in electrical and learned plumbing in the Coast Guard.

I feel like is time to put the fear to the side and get out in the field and from behind the books.

Whatever field you are working in, tell yourself, “I am where I am because I am choosing to be here.”  

Leaving aside if the JV is the best way to fund and assuming its not a scam than the fee is probably a very wise business move because a large percentage of the deals you see are from people who are delusional or are not taking numerous things into account (delays, closing cost, wrong comps, time, etc.).

I've never managed books for any kind of investor, but I'm a quick learner and excited by the possibility of getting my feet wet in the field of investing.
