Small WP-site needs makeover

I have really simple wordpress site with only a frontpage and 2 'pages', I am not using it as a blog. The template is this one: [login to view URL] Now the color theme is grey, white and black - I need it to spark! I am going to sell this product: [login to view URL] The template should have the same color theme. It should also make people wanna shop. Remember, the product is for mucle growth, so the color theme should be muscular. The job: Change the colors on the background, text and make a new logo that fits in.
