Use the Thai Embassy website. The STV Special Tourist Visa 90 initial, then 2 90 Extensions available at Thai Immigration. As said - you cannot convert the STV in Thailand.

This bank report will be used by Thai Immigration as your proof that your monthly funds came from abroad.

For an O-A visa it is processed in the Thai Embassy or Consulate in your home country. 800,000 Baht Equivalent must be in the your home country bank account. For the first time out trying to use 12 months of 65K Baht Equivalent cannot really happen.
A Non O 90 Visa should be able to be obtained. This Non Immigrant O Visa can be Extended inside Thailand for one year at Immigration by meeting the 800,000 Baht in a Thai Bank.
A married couple (non Thai) can do this: One spouse is primary - files normally... the other spouse applies as a Follow On and does not have to file separate financials
A Non O 90 day visa can be applied for at Thai Immigration after arriving on a tourist visa. Then extend one month to allow time to set up a Thai Bank Account and have the money in the account for two months
