A song consists of the lyrics, the melody line and the chording.
If you
CAN"T sing or play an instrument, then you've got to either learn those skills or try to hook up with someone who can do those things for you, preferably by collaborating with someone who shares your concept of what you want the song to be, rather than paying someone to simply put it to music without having empathy with your goals. (There are lots of organizations out there called "Song Mills" who are more than happy to do that for you for a fee, but whose only interest lies in taking your money, not producing a song that can become successful).
Writing the song out in a music notation, however, is basically unnecessary and probably won't help you much, even if you learn to do it, because the vast majority of musicians, (with the exception those in school bands or orchestras)
CAN"T read music.
If it's true that Bernie Taupin couldn't play or write music, then, he was extremely fortunate in his companions because they did play, liked the lyrics what he had written, and became his collaborators, (an option that is open to any pure lyric writer, but works out and brings success only rarely).
They put it all together, and played and recorded the whole, with any written score being an afterthought put together by a specialist employed by the publisher.
If you still want to print out the notation for your song, yourself, there are composition programs for those who know the basics on one or more instruments (but are not practicing musicians) to fill out the whole from the 3 basic units, of Lyric, Melody Line (one-noted on a keyboard) and Chording (worked out on the guitar with the help of some knowledge of music theory and that is, in fact, how I have fleshed out 17 of the 55 songs I have
written, (which mostly consist of only lyric and chording with the melody line in my head), winning 7 Honorable Mentions in various Song Contests in the last 5 years and a 2d place finish in the Country category in the 2003 Billboard Song contest.
Despite that, I have yet to get any Publishing Contract or have any of my songs recorded (except as demos done by me or paid for by myself)
