Screenshot creator for the Apple App and Google Play Store

I am looking for a freelancer to create a screenshot creator for both the Apple App Store and Google Play Store. The design style preferred for the screenshots is bold and colorful. I need additional graphic elements and text included in the screenshots, but I need the freelancer to create them. Ideal skills and experience for the job include expertise in graphic design, app development, and knowledge of the requirements for the Apple App Store and Google Play Store.

I will provide you our current App and Play Store URL when we talk in details.
