Need a Songwriter/Vocalist

I'm currently building a catalog of music specifically for syncs. I need a songwriter who can help build this catalog. There's no budget for this but I do have real opportunities lined up for the songs to be placed.

Additional info:
I'm an independent artist not affiliated with a record label. I'm looking for a female singer. . I don't have a hard deadline for this. I'm interested in hiring a pro who's worked on hit songs and have the budget for that. I need all the vocals recorded (lead vocals, harmonies, stacks, ad libs). I need help writing both lyrics and a vocal melody. I will only use the vocals for demo purposes. Not for release.. I'd like to use your name as the vocalist.
