Okay, now a few fair years ago I saw "Everyday Thai for Beginners", I never bought it because of the title!
Face it, at that time, I wasn't a beginner! Then one day I opened that book and WOW, it blew my face off. That's one killer book. Good structure, good method, good practice, albeit with NO karaoke, so if you can't read a lick of thai it's worthless.
A personal observation; there's NO need to whore your product (by that I mean; sell it cheap) for this niche learn thai market. IF it's a good quality product and IF in fact after people work thru it they benefit from it, it's worth what ever you wanna charge.
That whole "my price is cheaper than your price" is a losing proposition outta the gate. You'll go broke, just like many of the thai language schools hawking ED visas have. tryin' to beat the competition's price.
Man, I don't mean to argue with you, you know that. I learned thai "different" from everyone else.. It's just what I did.
Actually, I never ever got into reviewing thai language schools or writing about how I learned thai for money. I got into it because NO ONE out there was doing it.. I don't make diddly-squat off my reviews no matter how many students show up at a particular school saying they went their because they read my review! I wanted to know what was what in the market place that's it..
If you're ever in Bangkok, gimme a call, send me an email or whatever. I'd like to meet up, chat and see what you're really about with this concept.
While I'm a nobody in the "teach thai to foreigner" marketplace, if you got something good, I don't have my head that far up my own ass to say your product is worth what ever price you put on it.
Again, good luck, happy new year, and take care
