Music distribution

I’m 75 years old; have never performed publicly; am a very limited guitar player. However I wrote a song each year for my wife ( now deceased) and have put them on YouTube with mostly blank videos. 42 of them. I’m hoping someone can help me get the songs on Spotify or similar. I’ve produced a book to accompany the songs. They range from mediocre on down, but have sentimental value as they are. I’ll pay, of course. Anyone interested?
