First the short answer: You can "test" your subordinate login perhaps by logging out of your own site first in the top right. 'Just an idea. I do not have subordinate loggers.
Also, as per your first post, I would simply monetize this site, not build another site for monetization. If the one advising you to start another site does not have reproducible success doing this he or she should not be recommending it to you. You could, on the other hand, build a T2 for listing other Chiropractors – even offering them a C2 page for them to write their own original page in advertisement of their practice or products. 'Just an idea. I sure wish I had one site! I definitely would not have separate site to monetize the same niche. For one thing, it could cause your visitors confusion.
Another idea in answer to your first post: Why would you want to outsource monetization? It's generally a set it up and go sort of venture, a one time effort. Why specifically would you want to give someone else access to your site?
Now to your big question:
Suggested charge for a T2?
You can see the prices I charge on my order pages (top nav on the left), yet with you being in the health industry, I'll bet you could charge what Joette Calabrese does. I bought her program hands down. She's like you and gives away a ton of info for free, yet also sells courses. This is one of three products of hers that I've bought:https://studygroups.joettecalabrese.com/
Or this one might be closer because you might not have the course and video elements:https://joettecalabrese.com/product/BabyGrande.html
I've often read that $37.99 is a psychologically good price in that range and I felt that way myself when I bought; especially since I'd bought her other product at $49. Reading her next page though, urged me to buy the CD (she's got a super strict sense of protecting her copyrights…. so I did not want to risk messing it up by making a CD of the info for "just in case" as I suggest my customers do with my own downloads. I'm in her Facebook group and she would know me….) AND I bought the printed book - $60 worth. (No way will I print and mail! I do not have the time, and haven't the time right now to set up something like CreateSpace. You may….)
What I've found is that I've been able to make a separate T2 as a catalog/store page with reusable blocks nested with price reusable blocks. This way when I want to add a product or the price to a product on another page, all I have to do is pull in the correct reusable block. If I change the price or description on any page, poof! It's changed everywhere I've used that reusable block on pages and nested blocks. I LOVE reusing reusable blocks!
Several years ago when we improved our coloring pages on both sites so that visitors could type on them before printing, we updated some of the artwork and increased the price from $4.98 to $6.98 and found that there was no diminution in sales, or at least the money stayed the same or better.
Why .98? Because I have these set with E-Junkie to allow affiliate sales. I could sell physical books with EJ and do sell CDs. You might like SendOwl or something like Tobias uses on his Homemade Gifts Made Easy site. With an even number at the end, the affiliate commission divides evenly.

Where do you publish your T2s, Mary?
Well, my downloads are not also web pages as in your case. I think that you can edit and publish your T2s and T3s (chapters), and heartily recommend that you do. Edit the text of the pages to remove the contrived lingo you had to edit for Adsense and to remove the coding. You can add better images, diagrams, and places to keep notes as Joette does above in her books and courses.
Once you have all your T2s in books, you can then offer a bundle for a reduced price from the cumulative each price. I think that Ham Radio Claude has done something similar and perhaps Mike from Florida Back Roads.
My downloads do correspond to the different T2s: Math worksheets download with the Math T2, Phonics worksheets for phonics, etc.; yet they are not the text of the web pages at all. There are worksheets on nearly every page of my site. Rather than hunt for each one, many of my visitors would rather buy the download to file in their own computer rather than scavenge through my site for the right worksheets hoping to find the complete set. They do buy, even though they are totally free on the site! I can send you a free download if you would like to see how it works. (Offer stands for others here, too. Just contact me through the Affiliate contact form at the link above.)
So, back to my notes above, I publish the worksheets on most of the web pages, yet I sell the worksheets from what I call an order page where a visitor can "Buy Now" or see "More Info" on another T2. On PrintNPractice I used a keyword for the file name of the order page T2.
I hope these notes help.
