Animated gif for E-commerce Site and Image Editing

I need an animated gif for my website. The theme of the gif image must be horror gothic style. Dimensions of the image will be around 750px width * 220px height. I will send some images to be used in the animated gif. Further details will be discussed on project start. Update: I have around 22 images which i need to be retouched using a similar theme to that of horror or goth.
