The kind of mentor you need won't come cheap, how much are you willing to spend on a mentor, not someone who is going to spoon-feed you a strategy.
Haha don't worry, i am not interested in te slightest. But you won't get what you are looking for for free, at least not if you want good guidance and mentoring, as in everything: you get what you pay for.
Do some research and you will find out. A few reasons should be the forex market isn't regulated, brokers can quote you whatever price they want, they control the spread, can and will trade against you (not on an individual basis), ... If you are serious about trading, trade a serious market.
If you don't want to go for individual stocks or options you are better of trading futures like ES, NQ, CL, GC, ... And if you really really want to trade forex then at least do it with the FX futures such as 6E.
It's that or Forex if he doesn't want to go for individual stocks or options, easy choice to me. Well, there are a few other options but those are the major ones.
