Everything in Thailand can be done two ways: Officially / yourself or through some (sometimes shady) agent. I was referring to doing it yourself. This would involve going to the Department of Land Transport. For conversion, they might require you to have a translation / confirmation of your national drivers license by your embassy (costly and annoying ~1800 baht) + residence certificate (500 baht) + watching 1 hour video + paying around 300 baht for the actual Thai drivers license. Due to inefficient bureaucracy, be prepared to lose at least one day over this.
Unlikely. Only the issuing country of your national driving license can issue those. I doubt they would issue you one remotely and send it to Thailand.
You could alternatively consider getting a Thai driver license. They are rather easy and cheap to come by. Either make a complete new one, or have your national license converted. The latter might involve quite some bureaucracy.
