You're right, it doesn't take a lot of effort for someone who knows what he's doing, so I am not going to go on and on about that and try to justify my skills to you.
Instead, I can say what makes me stand out from the rest is the fact that I understand and know comedy, which in turn can further help to get the most out of the joke by having the video edit play alongside with the writing.
Other than that, I can help you with the jokes and funny ideas, I'd do that for fun because I enjoy having a good time. It's up to you how involved you want me in this, but I am saying that you're safe on the editing side.
