An ongoing client I work with is Andy of Andy's Airgun Reviews; andy asked me to develop a logo for him based on the channel name he was wanting to use for youtube.
I have since helped set him up online in social media as well as developing a full corporate ID including Vector graphics for logos and elements for his video production. Andy is now becoming the market leader for his niece on YouTube worldwide.
I have also developed the sting/intro for Andy and his client Drapers Airgun for use on social media.
