I love people that say teach me to make X. That's some sales pitch why you someone should even consider it. I've seen people ask this stuff and make these posts for years and you really see why the people lack success. They don't know how to sell.
If you're going to make a "hey I want you to mentor me" post for gods sake put what you bring to the table and sell yourself. List your skills that someone might be needing.
Example:
Hey I'm a great coder that builds in frameworks and knows OO coding very well. I also have some sweet graphic design skills here's a couple examples of my work. I can dedicate full time to this business and you'll have my undivided attention, I just want to learn. I've tried X, Y and Z and had minor success but I'm looking to take things to the next level and would like to find a mentor to work with ...... you get the point.
Now I'd contact that person
