Verifying Business Model? Would You Sign Up Today and PAY?

If you're able to tell people that with your system they'll be able to generate 35 to 45K per year, you can charge a boat load.
However, to optimize your sales, I would suggest a tiered pricing system. Because I have to assume to buy the 'full boat' package would be a barrier to entry to some.
To that end, possibly consider 3 packages:
* Bronze - access to all the videos and updates
* Silver - bronze plus (set # of emails and skype calls with you to get rolling)
* Gold - bronze plus weekly (within reason) access to you for coaching and guidance, plus lifetime updates

That strategy can be very effective because it'll also really help you identify your market. Depending on where the most people sign up, you'll know where to concentrate your efforts.

The challenge that comes with teaching people how to run a "real" business, while charging a monthly fee for it, is that a large percentage of opportunity seekers will unsubscribe once they find out that making even as little as $30,000 a year requires an investment of serious brainspace, time, commitment and a significant amount of additional funds in order to make their business profitable and sustain it for the long term.

This is why these one time $37 "do nothing and make millions while you sleep" push button scams sold so well a while back, and why $5 WSO's containing just one tactic still sell so well. Most people don't want to face the reality of what it really takes to setup and run a real business venture, but would rather be sold on a dream for a one time low fee.

Unless you can promise folks that the monthly investment in your membership is all they will need to spend, most will not stick around after the first month or two. Thus you are better off charging a one time fee, in exchange for access to a product such as an eBook or course that teaches your business formula.

is this a online or offline biz as that will be a critical price point difference as well

You are asking people to guess what you should charge with no research, no knowledge of the product or how good a teacher you are, and no idea what the vertical is. Our guesses have zero value as guidance to you.

I do however, agree that you should at least consider a tiered pricing structure, which would allow more and more access to you as the price goes higher.

I know it is common in selling courses to call videos "one on one" teaching, as it is common to call a report broken up into a number of emails "personal coaching", but please don't do it; it simply isn't any more honest than calling a public bus "personal limo service". "One on one" means what it says: you are live, teaching one person directly, who can ask question, and gets the teaching tailored specifically for them, not that 200 or 10k people are able to watch your video and pretend you're only talking to them.

Save the terms "one on one" and "coaching" for your highest priced offers which are high priced because those things are actually true; meaning you are actually required to teach "one on one" rather than just saying the words.

That is why it has high value, and why the terms are misused constantly by marketers to falsely pump up the value of their offers, and the misuse means you have to really be explicit when you actually sell the real deal, so people won't mistake you for one of the dishonest marketers who call a video made for as many viewers as possible, a "one on one" lesson.
