I realize that, its just amazingly hard to edit and upload video. The workflow for images is much more sorted.
Need a lightroom type deal for video
That's why you can still charge hundreds of dollars per clip and there are still a few good years in the footage business left. It's good that it's hard.
Just use After Effects or Final Cut. The workflow is not more sorted for images, it's just that video takes more time and involves more data.
You can quite easily do 20 clips in two days (film, edit, upload to multiple sites). Ten days full-time work: 100 clips. It's not THAT hard...
For one person getting 500 clips up in two months from scratch is not an impossible task at all. But of course, you have to treat it like any other job and spend the hours.
I'm very new to stock footage/images and have a lot to learn, both about the business, and improving the quality of my work.
I like your math of 10 clips a day, and do see this as doable, timewise. My current issue is figuring out subjects and items to shoot. Not sure I can come up with 10 ideas a day, or even near that. Any suggestions on getting the ideas flowing?
