I need help with lyric writing, music writing and mixing

I am looking for someone to help me produce a song which I am writing. I love singing and know what I like but I'm not much good at the actually music and melody's part of it... I'm looking to have a song similar to Melanie Martinez as I love to write in a similar style. I have a few requirements but I would like to work alongside someone that knows their stuff and can produce something like this! I have a fairly low budget as it is more a personal project.
You can find Melanie's music on you tube... songs I love of hers are:
