Great question. Here are a few suggestions.

light - natural light instead of paid lights video - use your built-in webcam or phone audio - do you have Apple or Android headphones that come with your phone? If not, I'd say you'd want to spend the money for a cheap headset if you can swing it.

Hope that helps

James Q Quick Thank you so much for your reply. Yeah, I do have headphones which may be a good option to start with.
