I need a full song minus vocals

I'm new to music production, looking to work on a whole song top to bottom. I want a happy pop Dua Lipa ish beat like Down Low on your profile. Please let me know what parts you can do and what the budget would be.

Additional info:
The song has less than 10 tracks recorded that need mixing. The song will be released commercially. I don't need to use your name - you can be uncredited. I'm looking for a female singer. I need help writing both lyrics and a vocal melody.
