must it be england? tbh i think its the easiest lower league to manage in FM. I mean that if you already have quite good knowledge of english football and had experience through FM with english football(which most people have lots of lol).
you should try another league, maybe Sweden. like Roy Hodgson etc. Build up from another smaller country league in europe, build a bit of reputation then move to a bigger club, fail come back to the country you were in, have bigger success then go to another big club this time succeeding or something in the fashion.
if not you want to take that dangerous route, try a big club from start, spend on known players. win trophies and brag about it!
but from experience i dont like to go lower than league two.
