Needing nutrition help

I am located in the Nashville area and looking for a good nutritionist that can help me with my diet. Bonus points if this person can write me out a meal plan that lists what to eat and when.
For reference, I have always struggled with my nutrition and knowing what to eat and when. I have been actively doing HIIT for the past year and feel like I have plateaued. I feel like this is because of my nutrition and my lack of knowledge. My gym does provide me with use of the Avatar app but they don’t provide me with guidance on what exactly I should be eating.
I am not opposed to following a meal plan that is laid out for me. I honestly think I would do better with using the Avatar app if someone told me what exactly to eat.
Any recommendations? Thanks all in advance for your help!

ETA: I am mostly looking to tone up by gaining more lean muscle mass and losing body fat.
