Thai driving licence

A wee bit of advice please: I have an Irish full licence and my THai wife has nothing. I wish to obtain a thai licence for a car and motorbike and my wife a motorbike only. I am aware that I need a proof of address certificate and letters from a clinic, its the next step and associated costs I am very unclear of, do I have to go daily to a centre as I believe my wife must and I live in the dark side and have no idea where the centre is, thank you for your anticipated assistance

I Googled, 'getting a drivers license in Pattaya' and there was plenty of information available, even maps.
