In order to mentor, the champion must be able to play with you. When I play with others I am sometimes asked to give advice or answer a question. I have no idea how many rounds you have played with others, but I would suggest you audition some champions by playing with them. Naturally this will also mean that you might have to expand your fiends list. (Really hard to set up a game with someone not on your list.)
The other aspect of improving your game is to play. You have played just over 900 ranked rounds in the 26 months that you have been a member of WGT. I would suggest playing more, a lot more, in order to push yourself forward. Also, play lots of practice rounds using the mulligan option on every hole while making a chart of the greens. Much of good scoring depends on where you are on a green. If you don't know where you want to go it is hard to get there.
The mulligan option along with the tee shot data option are great tools to learn about spin. Those mulligan shots that you take, when repeated with different spin, will illustrate how your clubs and ball of choice perform for you.
There are no secrets about how to play this game. A mentor might be able to help you focus on areas of your game that will help score better, but you will have to put in whatever effort is needed.
