Sing a song for me.

Hello, this is going to be really interesting , we want a song for my short-film to be played in the BG . The song length should be 4 to 6 mins. approx. All we need is a song written and sung by some talented person with good BGM . The theme is "friendship" . Here is the good thing , we are sending this movie to Cannes Film Festival - 2015. ** P. S - You will get credits in the movie. We want you to write only a few lines about friendship and sing it ( with Background Music ). We want it to be simple yet cool . Our budget for this is $50 USD. Our requirements are the following : 1. Write a song. ( No existing song you have to write a new no existing tracks ,only a few words ) 2. Theme is friendship ( Between a boy and his dog ) 3. Length - 4 to 6 Minutes. 4. Both male or female voice is fine. 5. The music should be light and we need more than a single instrument playing at the background. 6. Language of the song is "English". Hope you will come up with your great ideas. Thanks !
