You won't be able to use 12 consecutive months of transfers. The non-O visa itself and the first 1-year extension of stay can only be obtained 2 ways.
1) Income verification from your embassy
2) Proof of 800,000 baht in your Thai bank account
If your embassy does not provide income verification, then the only option is the 800,000 baht in your Thai bank account. You could have 10 years of monthly transfers, and it won't matter. The ONLY option for getting the 90 day non-o Visa in Thailand as well as the first 1-year extension are the 2 options I listed. The SECOND 1-year extension can use monthly transfers, but the first one cannot.
