Heat map in R Studio

I am looking for a freelancer to create a heat map using ggplot package in R Studio using numeric data and specific colors I have in mind. I need to be provided with the codes. The dataset is already ready and needs to be turned into a heat map to be shown in a visually appealing way. The freelancer should have experience in creating heat maps from numeric data, as well as be comfortable with styling the look of it in accordance with my preferences. I am open to hearing suggestions from the freelancer for optimal visualizations of this data. I'm excited to work with you on this project!
