Seeking designer to create postcard and social media ads

We're currently seeking a freelancer to re-create a 4" x 6" postcard (front and back) and Facebook cover photo (for a fresh new look). We currently have a logo. Freelancer would be required to provide additional design elements (backgrounds, images of online products, etc). Please see uploaded files of our previous postcard and cover photo. We will also offer additional work after this project (website maintenance, social media posts / ads, etc).
