OK, so let's assume the OP is 100% serious and not trolling everyone with a joke. I'm going to outline the process to become a CCR instructor to give you an idea of the time/energy/effort to get to the top of the food chain.
"AIR DIL DECO CCR instructor".. This would allow you to teach the CCR course most people want when they start (aka MOD1), but does not cover being able to teach mixed gas on a CCR. The steps to get there involve:
1. Become an Advanced Nitrox/Decompression Procedures DIVER. This involves at a bare minimum, four days of your life and six dives. While there are some weak instructors that will pass marginal people through the pipeline quickly, if you're sincere about trying to be a real GOOD tech instructor then expect the process to take longer. Realistically, if you have never ever been in doubles or sidemount, you're going to spend 2-4 days of instruction and 10 to 20 dives to gain some level of basic comfort with the gear, then you may be able to complete the course. Realistically, a motivated person that is extremely comfortable in the water can go from "Tech zero to AN/DP diver Hero" in a week or two if they're diving every day and able to pick up on the gear configuration quickly. Most "weekend warriors" take a couple of months to get there.

2. Gain appropriate experience to prepare for becoming an AN/DP instructor. Pre-reqs to become an AN/DP instructor include showing proof of logging 150 dives (you probably already have this), 25 on nitrox (you probably already have this), and teaching at least 10 Deep Diver students and at least 10 Nitrox students (you probably already have this). I would also encourage the AN/DP instructor candidate to shadow at least 2 or 3 AN/DP courses to see common problem spots that real world students have and gain some perspective on how to structure an AN/DP course. Some things you may consider during this learning curve include:
* emergency procedures: this includes how much deco are you willing to let yourself and your students blow off if things go south?
* how many deco dives would you be willing to do in a day?
* gaining a thorough understanding of decompression theory, also look at modern info (ten years ago bubble models were all the rage, now not so much), learn how to cut contingency tables on the fly (aka ratio deco, etc).
* gain familiarity with a variety of different tech gear to be able to help your students
* gain some real world deco experiences, I would suggest at a MINIMUM you should have experience conducting 30+ deco dives in a variety of conditions/environments.
3. Become an Advanced/Nitrox/Decompression Procedures INSTRUCTOR. Standards for the IE are here.

4. Become a CCR Diver. That means pick a unit and spend a minimum of 5 days of your life taking a MOD1 course.
https://www.tdisdi.com/wp-content/u..._30_CCR_Air_Diluent_Deco_Procedures_Diver.pdf Please note, you can become a CCR diver while you are working on gaining experience before becoming an AN/DP instructor.
5. Gain appropriate experience. This includes both diving your CCR and teaching AN/DP. You must log 100 hours and 100 dives on the unit you first become an instructor on, and you must be certified as a rebreather diver (on any unit) for a minimum of one year before you can become a rebreather instructor. Although there are no minimum students taught for Open-Circuit AN/DP, I would recommend running at least a couple of classes to gain some experience. I would also recommend assisting with a few CCR courses during this time.
6. Sit for your CCR MOD 1 instructor evaluation.

So.. to go from "Tech Zero" to CCR Instructor, able to teach both Open Circuit Advanced Nitrox/Decompression Procedures as well as CCR MOD1, realistically you are looking at a minimum of 13 to 14 months of your life and an investment of anywhere between $10k and $20k between the rebreather and courses, not including travel/etc.
When you start talking about adding in trimix instructor levels, the time/experience goes up from there.
