I am sure if you went to any big CS university in your area you could find some grad student who well versed in the requisite knowledge in being a good C++ programmer (Like Algorithm design, linear algebra, discrete math), and have them tutor you, generally the going rate is about $20-40 an hour. I would also make it a point to make sure they are proficient in what they say they are, a good set of questions or something of that sort. Find someone who enjoys reciting what they know, and will let you pick their brain.
