Youtube branding

i want to start a youtube channel and need professional short intro with music, outro, logo, banner art, plus banner/logo for twitter, i basically want everything i need to look professional and just have to worry about dropping my vid into an editor, stick it all together and upload.

my channel is going to be about lego, i will do reviews, build timelapses and blogs news, tutorials etc. etc

my channel is called "the british brick blogger" and i want a fun playful theme, i can point potential candidates to see the competition so you know a rough tone/theme of that type of content.

cheers
