1 song mixed and mastered

Hi! I’m a home artist and have completed the writing and producing on a track that I have TRIED mixing on my own. I figured having another ear would be better than taking the whole project on my own. The engineering side is the one that I have trouble with. I would really appreciate some mixing and mastering work. It’s an r&b experimental type genre.

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'll need you to master it too if possible. I don't have a hard deadline for this. . I'm hoping to find a good mixer that can work with my limited budget.
