A marketing image for my Linkedin, Fcebook + Twitter page

Hello, I am looking for someone to make me a marketing image that I can put at the top of my Linkedin, Facebook + Twitter page which outlines our key services, I have attached 4 images - the first three images show the locations in which i will be putting the images and therefore may need 3 different sizes? the last image is an example of roughly the type of image i am looking for once you can confirm you can do this I will send you the exact key services I want and then you can play around with it and we can then decide whats best.
