Studying, Learning, and Expanding on Fundamental and Complex Aviation Concepts

Hi! Currently, I am enrolled in a ground school/instrument rating type class with the hope of soon obtaining my private pilot's license. Though I do have a fabulous instructor, he is a very busy man and is not always available to answer my questions, and/or into go a bit more in depth regarding topics of which I am struggling to develop an adequate understanding. I know that asking here is a bit of a long shot, but I am looking to find someone who is either a flight instructor or a pilot him/herself, and is willing to take the time to chat with me and to explain/answer questions pertaining to a vast amount of topics in preparation for various FAA tests, and ultimately my check ride! Thanks so much for any and all help! I really appreciate it!
