I need some Graphic Design

I am looking for a designer to create ad banners. These will be NSFW adult banners that will be used on adult websites for advertising. Applicants should have experience creating these types of banners and a portfolio or some examples would be appreciated. This will be a long term project so I am looking for someone I can depend on and work with to create banners as needed on a constant basis. These creatives will be needed in a variety of sizes as well as different formats for example some animated gif formats. Must be good with communication.
