We are seeking the creation of 3-5 header images for our website. We want the images to be informative, simple and high quality. We previously created some images which worked in the interim but overall are not as effective as professional images (see attached). We are open to ideas regarding the method of creation (e.g. illustration, cartoons, images, etc). We have no preference on the design program as long as the images are high quality and can easily be rendered on our website without lengthy loading.
Some examples of the kind of header images we are looking for are located at: [url removed, login to view], [url removed, login to view] & [url removed, login to view] .
Our current images are 980x312 however we are open to suggestions and changes based on the creativity of the selected designer.
