You can't PM until you have 15 posts - won't be long at this rate though.
I've found nothing works quite the way you think it does. You can go outside the mainstream path, and not just in Thailand, but you better be ready to have all sorts of problems if you do. I speak from experience here. Try and go as close to the usual path as you can, it will make your life a lot easier. You'd want a really good reason not to.
Obviously I don't know you or your situation, but you don't sound well prepared for what you're doing. I'd suggest you be very careful. I won't say don't do it, since I pretty much did it myself, but perhaps I can make a couple of suggestions that might help. Get a doctor to supervise, and get a therapist (or psychiatrist who does therapy).
You get the doctor so you don't accidentally kill yourself, but also because they can maximize the effects of the hormones without being dangerous. You might also be able to get hormone implants from a doctor and if you need to travel for hormones, or hide what you're doing, that's probably the best way to go. You won't be able to get that without a doctor, since its a minor surgery to put them in (its a scary thought).
The therapist can help you with any issues you might have, and the ones that possibly are coming if you get found out or your feelings get stronger. Think of them both as insurance against bad things that could easily happen.
It sounds like WarlockMaker has a good doctor, and you should be able to find more. You could try asking the doctor if he knows a local therapist.
If you get the doctor and therapist now you'll also find the next steps a lot easier if you need to - its a lot harder to get SRS without letters than hormones.
