Help! I need a new layout and I'm blog inept!

I hate my layout ... I need something new and fresh to go with my banner but each one of the standard layouts in blogspot all seem to suck when I click on them or look weird ...

Is there a magic place where I can get something trendy and bright that fits the page nicely?

If so how on earth do I get it to work?

Seriously when it comes to computers I'm as thick as bricks !!
