Can’t help but think the expenses were overboard. $3500 spent per video, including a producer, DP, food stylist, and editor? Surely videos of very similar quality could be made with a fraction of that budget if the fat was trimmed and it was approached more bootstrap-y instead of a full production.
You should give it a try. I do not think you will be able to do it for less at similar quality, especially with food.
I watched one of her videos and the sound effects were annoying, so cut those. Skip the color grading. Stick to 1 or 2 stationary cameras. At least attempt to learn how to edit audio and video. No idea what a food stylist is, probably cut that out too.
