You have money is account and even twice a year You have an income to support Yourself thru the year. You have abroad company where You can provide Your own letters proving You can work remotely. You have everything You need to apply for remote work DTV . I had overstay stamps in my passport and get DTV without problem as even they didn’t check it. Try to input Thai departure and Bali arrival stamp on the different passport page than Your overstay stamps and good luck.
May we know Your turnover You show to them for last 6 months.. Maybe they consider to low even 500 k is there ..? I would recommend go to the country where they still accept applications in person at embassy where the fee is paid upon approval ..
Based on my experience You don’t need to have 500k Baht for all the requested statement . You need to have them on the account at the time of application.
In my opinion after applying in Ho Chi Minh the 500K need to be in Your bank account at the time of application. Even they ask additionally to submit 6 months bank statement it was irrelevant that I had my 500k only for few days. The reason why they want to see 6 months transactions is not known. In my opinion is not relevant that You married or have children in Thai to apply for DTV rather than there should be another visa in Your circumstances but defo not so great as DTV.
