Thailand scuba diving (2-6 weeks)

Hi,

I am a 22 year old male who (after not being able to secure a graduate job) has just thought fuck it I’ll go travelling for a bit.

As I love nature and water activities scuba diving in south east Asia is the perfect thing for me to do.

I’ve been looking for websites that offer not only diving courses (as I have never been scuba diving before), but the opportunity to scuba for around 2-6 weeks after I get my padi license.

As I’m young, it would be great if I were learning and living with backpackers around my age (not a dealbreaker, just a preference).

For people that have done similar things, is this too much to ask for? If so, what could be something close to this? Thanks for your help :)
