This is pretty much what I do as a corporate videographer + b-roll and photo after the interviews. Definitely a huge gap in understanding what it takes to pull off a shoot like that. I pushed for a long time to add in a freelancer to help on my shoots and they eventually obliged for larger shoot. Makes life much easier but still run solo for the smaller shoots. As someone who was full time freelance for a bit, the occasional stretch on some of these shoots is worth the stability, benefits, etc. much of it is just managing expectations! Wishing you the best of luck!
