make music for my song. children's song theme

I have a children's song of my own creation. Some of the songs are in "Indonesian and possibly English". The song is for my YouTube channel. The theme is a simple children's song. The lyrics are just a few repeated sentences. The song is probably only 3-5 minutes long.

Your job is to create child-friendly music and replace the voice with a child-friendly singer.

This is very important.

I want the music and the singer's voice to be copyright-free because I want to upload it to YouTube.

If successful, I would like to collaborate with you long-term and build my channel together. Budget: USD 10–15 Skills: YouTube, Final Cut Pro, Sound Design, Video Editing, Adobe Premiere Pro, Audio Editing, Content Creation, Voice Over, Audio Engineering, Music Production
