13000 baht (about $430 USD) seems reasonable and you can learn better over a longer time period. I would be willing to support this fully with a total of $450 USD.
How can I send money to you?
Options (that I can think of, you may find others):
1) Western Union – you would go to an office and pick up the money, not sure if there is a location near you.
2) Mail US dollars in multiple letters – some could be stolen, but most would likely make it through. We could do a test with $50 or $100 USD. Not sure if you have everything needed to change money at a Thai bank as they did ask for my passport. If you don’t have a passport, it may be acceptable to change money with other identification. When I changed USD at the airport, there was no fee and they paid 31-34 baht per USD.
3) I can move money to a bank account but I would need the “routing number” (for US accounts it is a 9-digit number) and the account number (usually 6 digits).
You may have to ask your bank some questions to learn about option 2 or 3. Also ask them if there is any better way to transfer funds from a US bank to your account.
