GIF banners

Hi, I am looking for someone to help me create 20 animated GIFs for the google ad networks. These don't have to be to complicated (maybe just some slightly moving text etc). Hopefully if you are applying for this job you will be familiar with google display banner sizes if not you can see them here https://www.disruptiveadvertising.com/adwords/top-10-adwords-banner-sizes-you-need-to-know/

If you could send me some previous banners you have done that would be great.

Look forward to hearing from you
