The rest of you: if you dont have anything sensible to say dont say anything at all. I have found a divecenter in thailand that certifies you up to instructor including lodging, full gear and over 100 dives during 6 months.. That for 5000$ if you dont have any certificates.
That's precisely the problem.
How qualified do you think you will be with a maximum of 100 dives over 6 months? Will you be experienced enough to handle rescues, work with problem students and deal with the potentially life threatening issues that can arise. Or will you be a 90 day wonder with an instructor's card and less experience than many OW divers?
At 100 dives you are just getting to the point where you can take care of yourself. Never mind other people who are depending on you.
You should be able to handle any situation before you ask other people to entrust you with their lives. You should also be capable of turning out competant divers. 100 dives isn't enough to do that.
In addition, I can't imagine what type of gear you'll get. I've spent about 3k just on my singles rig, not including the dry suit. That doesn't leave much for instruction and training.
I can't speak to the specific shop because you didn't provide it. However, this type of operation does not have the best reputation for turning out quality instructors.
By way of comparison, my DM course took about one year to complete. I apprenticed during 6 complete OW classes, several Nitrox classes, 2 rescus classes, 2 first aid classes, a wreck specialty and more buoyancy classes than I care to count. I assisted during trip planning and management.
My AI course took an additional 6 months. I'll be finished next weekend.
In order to become an instructor associated with the shop, I'll need at least 5 years as an active AI.
By the time I go up the line, I'll have assisted hundreds of students. Even then, I'll work under supervision until the LDS is satisfied that I can teach independently.
Take your time, learn your trade and have fun.
BTW, I'd strongly suggest dropping the attitude. Your post suggests that you are looking for the card rather than the skills. If this is, in fact, the case, then please let us know where you are working to that we can avoid it.
