It may be difficult to come up with a mentor via a discussion board such as this. A mentor might better be sought in your local area, through your local association.
In lieu of a mentor, try these time-tested ways of getting off the ground and getting better:
1. Accept all the junior high assignments you can, and ask your assignor to match you with partners who can mentor you
2. Watch as many high school games as you can, taking notes on the mechanics of as many seasoned officials as you can
3. Get to know the rule book well, and use it to reference issues and topics brought up on this discussion board
4. Get to know the case book well, as it offers depth of application to the rules, bringing to real-life the principles found in the rule book
5. Get to know the officials' manual well, as it explains the 2- and 3-man mechanics you need to know
6. Ask your local association which basketball officials' camp to go to and register for it NOW. Go and learn in the crucible of the camp setting, and reregister to go again the following year
7. When you go and watch games officated by guys and gals you know, ask if you can be present for their pre-game, intermission, and post-game locker room meetings; don't go there to talk, go there to listen in and learn

Good ideas can also be found under a previous thread from about three weeks ago.

Don't be disappointed if you don't get someone to come forward as a mentor from this discussion board. That may be too tall an order to fulfill given the limitations of cyberspace.

Hope some of this helps.
