What I noticed is that is somehow hard to understand how to create the page. ( Click here, then there, then copy paste, then click publish, etc... ). If this process was more it would be awesome.
Keep going the good work! I checked your $1k goal and wish you all the best in achieving it!
Make steps have sub steps, so step 1 is use this template, step 2 is prepare the spreadsheet; sub-step 2a is "press publish", sub-step 2b is "edit title on the main-page sheet" Step 3 is "Publish!" With sub-step 3a being copy url, 3b paste, etc.
It requires changing the code a bit, but should feel simpler, since there's no switching back and forth, and some complexity is hidden inside the sub steps.
