One option is to float around a little. Spend time in Thailand as a tourist, then head to Vietnam for a bit, then maybe bali etc. You can always rent a cheapish room in Thailand and keep it running, even if your away a few weeks in another country. Just try to stay on a strict budget and enjoy your travels I say!
I thought you mean you rocked up to immigration with two "escorts!" There's me thinking I'm in for a bit of gonzo journalism here! Anyhow, sounds tough man!
I'd suggerst you try it for a couple of years first before you start making big decisions. If it's the case you want to do it full time, you'll have already got all the info you need. Tread lightly is the advice. My father has been out here for at least 15 years now. I can put you in his direction, but I'll warn you, he's straight talking.
I'm not sure, but I've had mates over the years who signed up with this school and they were in Thailand long term. I used to live near the place, it's on RCA.
