Music video for recorded wave file song/s for you tube or social media etc

I have songs I've written recorded as wav files in Dropbox. People tell me I should put them on you tube social media etc. That maybe I could make money from them or something. Don't know how or if that's possible. Think what I need is visual to go with audio. Whether it's film or just pictures but some form of music video to match audio recordings. It's basically singer songwriter songs. One man band. Acoustic guitar singing harmonica solos etc.
