The idea is great. I though of something similar and so googled on Steem to see if there was something similar. Since there doesn't seem to be any service like that I am planning to create one. @firsteganos your post popped up first in the results and hence I am commenting here :)

The app will basically be a portal where users can recruit guest bloggers to publish in their blog. There will be a revenue share between primary blogger and guest blogger. Since the share it transparent and is built into Steem posting, I think it will be fair to both the parties.

Over the time I will built info pages where you can look at all the guest bloggers under a primary blogger, their share of rewards and so on. I will be working on a MVP over the next month.

Please let me know if you would be interested in trying this out as it will make your process much simpler.
