At MOST consulates on the eVisa system, they require 500K for every applicant (one account with 1 million baht works for two people),
AND
they require proof the primary applicant HAS their DTV before applying for the "dependent" one <- meaning you get your DTV issued THEN apply for the dependent one
I would say you need to go to a walk up consulate <- Taipei and apply in person at the same time for both of the visas,
Taipei is a "walk up" consulate <- meaning there is no appt that needs to be booked to get in the gate, you show up in the morning during the application acceptance time and apply
If you're going to apply for a DTV which you do not in Bali but in Jakarta using the online system you have to STAY IN Indonesia until you get the visa approved (or rejected)
You can't apply and then come back to thailand on a free stamp to wait
