Create Simple 1D images/ebook covers

I am looking for someone to create 10 **Extremely Professional* Looking 1D (one dimensional) report covers for me and i wold like each of them to have a different look. I need the covers as a vertical rectangle shape not square image. I need you to give me each cover in two sizes ---one needs to be 960 x 1280 pixels and the other needs to be 600 x 800 and under 127KB in file size. both must be saved as JPG images. one will be used on the product page and the other in the book/reports. All images must be royalty free( i need to know exactly where you will get the images from to verify. This will be a work for hire, meaning i will own all of the rights to the finished covers. I need 10 covers for now but will need more in the near future. this project requires constant communication between us since each cover will require different textual content..i.e. Title, subtitle,Author, and you must be creative. If you have created 1D(One Dimensional Covers in the past please show me examples of your work....Thank you I currently have a book on [login to view URL] called shopping resale beats shopping retail and i would like a different cover created. covers must reach the customer and the content and pictures should speak to the buyer. I look forward to building a great relationship thanks.
