You are applying for an initial in-country Non-O based on a spouse to a Thai national at the Chaeng Wattana office.
You have to have a 400K Baht deposit as of the application day, but you don't have to wait for two months for the initial visa. Two months of seasoning is required for a 1-year extension, not for an initial visa.
You can apply for an initial visa until 12 Nov as long as you can get the required documents sorted.
You have to go to the CW office to get the latest requirements list ASAP. This is the sample list for an initial visa in Bangkok, but as you can see, it's 2.5 years old.
And don't wait until the last day to apply for your visa.
