400 i doubt you could do it for that to pay for all those things. Unless your in really remote thailand.
I lived there for a while. I had free place to live only payed for the power which was 400 baht a month cold shower no air con, no kitchen etc... and i got free training.
The only way you could do it for that budget is if you live at the gym with the Thai fighters and get free training in return for fighting. But its cut throat you don't make them money and you will be booted out.
Also Thai baht is very low at the moment 45 baht for 1 pound.
Its all good and well going to Thailand with good intentions of training everyday etc. Living like the Thai fighters do. But seen so many western's come then just end up on the nearest walking street.
