If a company has a proven and efficient trading system, elaborated through thousands of backtesting hours and years of brainstorming and team work, I am quite sure that 5K or 10K dollars to invest in each candidate would be breadcums for them. I would not trust a firm that is asking me 2K dollars to teach me something I am supposed to use to earn tens of millions per year.
I had to remove your other posts as they aren't contributing to the point of this thread (which is a comparison of trader scouting programs and info on the prop industry in general.)
In the first post of this thread, the differences between a traditional prop (what you are describing) and what these scouting firms are is clearly laid out... including what their business model means for the trader when it comes to conflicts of interest.
The model you are describing ultra competitive to get into these days thanks to an overqualified labor pool and decline of discretionary traders to make way for more algo traders and quants in the industry.
Scouting programs have a niche case where they fit pretty well in the current business landscape. They aren't perfect... and the companies running them are making healthy profits from the evaluation fees (though, you could look at The 5%ers as an example of where your max DD is basically your evaluation fee on a live account, so we are starting to see the scouting firm industry margins get tighter..)... but they are still a valid way to trade.
