Redesign (or new instalation)

Hi, Could you improve the design of this site?
I'm hosting. If so, please write your prize. thank you
This means wordpress install it, modify a template, mainly to make it accessible from mobile applications, right?
I need to sometimes replace those products and rewrite some lyrics, will it?
