based on this screenshot it sounds like you should be able to apply with 65K each per month. Once you get to Thailand, you must have the 800k in a bank account for a minimum of 60 days before you can do your one year extension. The 800k must remain in the bank for 3 months after application, it can then drop to 400k and must go back up to 800k 2 months before applying the following year.
