[Need Advice] Is my Concept Profitable?

Hello All,

I'm currently building a small gig here where I bought access to those WSO Download courses and repackaged their courses for my own.
There's around 4TB worth of Digital Marketing Courses, including the whole MasterClass series and MindValley and so many others from MOOCs (Udemy, Coursera, etc) - lastly also a few hundred E-Books

I'm currently in the process of uploading them all to my Shared Unlimited Google Drive - as well as to my Mega Storage. So I have multiple backups just in case.

The site's landing page is still in the process of development. But I think the main concept is a Digital Marketing Vault, just like those WSO courses only dirt cheaper.
I believe this is a churn and burn method - but my target sales are only less than 300 at most for its entire existence. At around 30 sales it's already break even.

I plan to charge just $29 for access to everything. That's like 70% off compared to sites like Getwsodo. I plan to launch by January 2021.

I mainly just need the money earned from this to be used as capital for a couple of niche sites that I'm also currently developing- at least that can be sustainable in the long run.

I plan on advertising on FB ads and other forums and other sites as well; Facebook Groups and Reddit mostly.
I also plan to add an affiliate program to it just for the sake of it - if it sounds feasible why not right?

Is this profitable? Is there a way to bump the sales if possible?

I think those services are in demand for quite a time now and are not planning to decline.
For your niche, I can recommend having a telegram channel, where you can showcase your courses and lure new users to your site with promos of free content. There are a lot of case studies that can back up the effectiveness of advertising there.
