Yes Ingsacha, the amount js correct.
But the plane ticket is not, like I explained in my last message.
If you want, we can do this directly you and me, no agency. If we do like this, you don't need to pay in dollars and pesos: pay only one time in Bahts.
and if you want we can meet one more time tomorrow afternoon (I am leaving tomorrow night).
Thank you Ingsacha.
