Hey there,
I checked out the youtube video that you linked. I could definitely create something like that. I think it would be a pretty fun project for me. I've done image manipulation stuff in Javascript before, so I'm sure I could do it relatively easily.
If you're not sure about hiring me, I'd be willing to create a free rough sample first, for you to see if you like my work.
I'm looking forward to hearing from you. Thanks.
