Cake Business Postcards/flyers

Hello! i am looking to have someone design a postcard/flyer for me. I have a rising local cake business and dont have time to design my own. i did design my business cards (which are already printed) so id like them ro reflect it. I attached an image of my business cards so you guys have an idea of my taste. im very simple and im super into purple. mostly darker purples. they need to be 4x6, or 5x7. im still trying to decide what size i want to order from the printing place. ill provide images of the cakes id like to have on the postcard. design should be for two sides. i require a photoshop file with all layers included once i have chosen a designer and i approved a design. please let me know if you have any questions and happy bidding!! =D -Hilda
