Anybody know how to make intros?

[SaVi Mars]

Hey guys I am a youtuber and I make videos daily and have realized that I am missing something that I think is really cool: An intro.

I was wondering if you guys could or knew anybody that knows how to make a decent intro. Just something like 10 seconds long, and simple. Please let me know!

10 seconds is a bit long, something around 5 or 4 would be better.
