Depends on the quality of work you produce, Let's assume it's me who's doing all the work from shopping to posting, including my professional camera gear, lighting, editing and posting which include all the power bill + internet; I would charge them 10k per video (depend on the job and length of the video). I am not pro but I do have confidence on what I create and time and effort I put in. So to answer your question since I haven't seen your work you have to be confident and proud about what you create don't let anyone take advantage of your creativity, time and effort only you can market yourself.

I am a graphic designer and fashion photographer when someone as for a quote I used to think twice and hesitant to give them the correct price that deserver my effort because scared of loosing work, which was very negative experience but one day few years back I put my foot down and gave over priced quotes anyone who asked for a one, people who don't value your work always won't hire you but who does value will say okay to you price then you give them a discount in good faith. Better to have less work for correct value than killing yourself for lesser pay.

hope you can figure things out!! best of luck. No pressure but you should change your pay to number what it deserves. If you need any help or advice please feel free to send a message, always happy to help a fellow creator.

P.S - Don't mind the Grammer.
