I like to have full control of the players hired to my squad. However when I'm managing low leagues clubs usually I look for free transfer players. Free transfer players are hard to scout because they don't play matches, so I try get then on a 2 weeks trial, at least, to reveal their attributes and get some staff evaluation about player potential. Aside check player search on scouting section, I also ask for free transfer / loan recommendations to director of football. Sometimes loan market players also accept a trial, because scout them will take lot of time, due staff low skill and non professional contract.
That's the kind of help and advice I usually ask to Director of Football
