Create gif animated pics for tumblr from adult videos

You need to create gif animated pics from videos. The gifs should be tumblr compatible, watermarked with a small text. Videos are in adult porn industry. I will give you my account of one of the most popular adult site, and you make gifs, most important your gifs need to be high quality, not crappy ones, as image quality and also as scene. For now I need 100 gifs, for each gif you'll provide me the title or link scene. I don't have time to learn and make them. I know the internet is full of tutorials on how to make high quality gifs.
