Facebook creatives

I am looking to hire a talented freelancer to work on creating a number of creative pieces for Facebook. Specifically, I need both images and videos that adhere to a specific theme or guidelines set out by me. The number of creatives I need is more than 7 (The number of creatives may vary.). The freelancer should be skilled in creating these content pieces and should be comfortable working within the guidelines set out by me. I'm confident that the right freelancer can help me create amazing content that will get noticed and create a strong impact.
