Need new vocals for my original song.

I have an original song that I recorded last year at a studio with the help of a song arranger. He added the instrumentation, mastering and background vocals per my specifications. I laid down my vocals over the other tracks. Although it was superbly produced, I think new vocals by a professional male singer would make my song much more appealing. I am not a professional singer. This song is very good and adding better vocals and maybe even more orchestration would definitely make it a lot more marketable for radio airplay.
