Hey John - your ideas are great but I just started the video and it's REALLY hard to understand your voice. Best Buy sells inexpensive mics; you can also just set up an iPhone (or any phone, actually). I was using my wife's iPhone 14 for best quality, but discovered most people were perfectly fine with the video quality of the iPhone 7.

Now, I use Logic Pro for sound editing but Camtasia and Loom provide much simpler sound editing tools. You have a great and important message; I would strongly recommend investing in some better video and sound editing equipment.

in fact, for about $14 a month, you can get unlimited Zoom and though it's not great quality, just do a Zoom movie recording.

Good luck; really good stuff. (and I'm putting off getting down to writing some blog posts at the moment, so with that, I'm going to sign off and write at least one!)
