You will both have much better luck if you jump into it and return with specific questions. You'll find that the people here, and just about every other forum, are more than willing to answer questions and help you get a foothold. Conversely, you will find that you will not get much help if you aren't specific about your needs. Wanting a teacher is too broad of a need. Forum members are generally very helpful people (at least in the tech space) but you'll find them more willing to help if they see you've put some effort in. It's very much a "get out of it what you put in" kind of mentality.
If you're interested in learning Flixel I strongly recommend you begin here: http://flashgamedojo.com/
Play around with these tutorials and samples. Then choose a very small goal. Wanting to build an RPG is a BIG task if you're new to this. Instead focusing on wanting to build an RPG, focus on learning how draw a map to the screen, then maybe how to move a character, then maybe a separate exercise to handle a speech bubble system or a drag and drop inventory...
If an RPG is what you want to build, break it into VERY tiny exercises for yourself and return to the forums with specific questions about what you're struggling with, showing what you got to work and where you're stuck. There's nobody out there who can teach you how to make an RPG, you can only learn the building blocks. I suspect that if you learn enough of the pieces (like mentioned above) you will begin on your own to see how they might all fit together.
You won't get anything "right" the first time, but that's mostly because there aren't necessarily "right" ways to program something. Some are more efficient than others, sure, but that doesn't mean there's any one right way or that any other way is inherently wrong. The important thing is just jump into it. It's a fun process, learning how to program, and very rewarding. And you will find that in learning something specific you'll stumble upon all sorts of other tangential learning opportunities that will help you come to understand how each new thing you learn will fit together to build an entire RPG or whatever genre you want to tackle.
Good luck and have fun with it
