Create Banners To Go On Website

We need somebody to create 20 website banners. 10 will be 1000 px in lenght by about 300 px. The other 10 will be 1000 px by about 100 px. We have the images we want to use, but we would prefer somebody who has a membership to a website such as Shutterstock because we may need additional images in order to complete. The images used MUST BE LICENSED. Must have good communication skills in English or Spanish Must have a SKYPE account and available for chat at times. This is a small project, but we are interested in building a long term relationship with somebody because we very often need to make changes to our website and need different art. Thanks!
