KDP book promote and advertise. -- 2

I am seeking a freelancer to help me with my project on KDP (Kindle Direct Publishing) to promote and advertise my book, a Fiction novel, specifically aimed at adult readers. My goal is to increase the visibility of my book, reach a wider audience, and, hopefully, increase its sales. I would prefer the freelancer to only use online marketing strategies, as I am not looking for physical marketing materials. The strategies should include, but are not limited to, ads on social media, giveaways, press releases, and other organic outreach. I am looking for someone who has experience in this type of work and is committed to helping me reach my publishing goals.
