KLIFA in Senai might offer PPL if there is enough demand. So, call them to register interest and get your friends to do the same.
They will be able to help obtain the relevant visa too.
Alternatively, a PPL in Australia will be fairly quick if you are willing to do it full time. Only 45hr minimum. Assuming you are willing and able to fly 2hr/day average, that will be 23 days, add 30% extra days for weather and other challenges, that's about 30 days. Cater extra time beforehand to get your SPL issued (you can't solo without it).
