There are so many possibilities for audio (voice work) or video (face videos or powerpoint type videos) and you can get paid for your efforts too.
As I suggest elsewhere, try selling your work on Fiverr.com first. Learn from your clients there what people ask for, what they do or do not like... and then earn more once you understand audio and video work better!
Simply hit the FIVERR link above -- search for AUDIO and look at the variety of people ready to do audio for others.
So many ideas, so little time.
Look at the fees they are asking for, what the gigs are -- and imagine gigs you might offer to do with YOUR Voice!
Fun and income on the side. Raise your fees as you get more gigs and more customers!
I purchased Videomaker FX when I started to make videos and I still use it. It's easy, fun, and really versatile. You have lots of control OR you can use their templates and just fill in the blanks for the video you need. Learn this app, then sell your services locally or online.
Loom is a cool application where you can record yourself in a small bubble on the bottom corner of the presentation screen as you speak about each slide.
