it seems that I found your post a bit late. I am more or less the person having taken over Dr. Yanni Zack's column as he does not post here any longer.
I would love to give you some helpful advice if I could. But according to what you said in your post, the info seems a bit scarce, and if you could give some more details of how and to what extent you intend to get started in ESL, I could certainly give you a much more concrete and helpful advice!

Good luck!
