Need Gospel Instrumental Tracks

Hello I am gospel writer and I’m writing songs for a children project. I have the tempo and keyboard tracks already started I just need the other instruments added that will be able to catch the attention of the people but smooth listening sound. I want to keep the keyboard/piano track that is set forth and other instruments just added to it

Additional info:
The song has less than 10 tracks recorded that need mixing. The tracks are cleaned, tuned, and and the song is ready to be mixed. I don't need the song mastered. I'm an indie artist. I'm hoping to find a good mixer that can work with my limited budget.
