Can someone here please help, i need to write my daughters name "Kasey" in Thai. Can someone do this, or direct me to a site that does.
I have tried a couple on line sites and they are very different in there result.
I believe there are a few forms of Thai written, please use any.

There are several different ways to write English words into Thai, depending on what rules one follows. If it was me I'd find a Thai person nearby - go to the nearest Thai restaurant and ask the girl behind the counter.
