Ask HN: Rails mentor for my first webapp

I started learning Ruby and have gone through Michael Hartl's tutorial. But I still have no idea how am I going to build this webapp I have in mind.

I am looking for someone who can mentor me, teach me and guide me on how to do this. I am ready to pay for their time and energy on me. I just want to do this myself.

I am presently in Sydney, but happy to work with Skype for remote.
