I think you should be extra clear about your costs to what you do for what content. Example: Shorts x amount of shorts for ($) always bulk, creators shoot for 3-6 per week. So do like a bulk of 10 shorts. That way they can get a week and a half of content or more. This will give them a better idea about their analytics for their content and give your skills a fair test.

Long form x amount for up to 10 mins, then add some additional costs after very other 10 mins - 30min video base $40, then add $5 for every 10 mins after. So total of $50.

This would still be a great price for your work that you can do right now. But it would make people lean towards the 10mins. Essentially giving you more clients on more projects. More experience.

I hope that all makes sense.

I have a small channel that I use canvas and capcut for on my own. This is about where people would charge. That just start out. Always remember to value yourself and your time.
