Logo design

We need a professional logo for a new fitness supplement website. We are looking for the branding of the letter 'Z' with a suffix. We plan to use a stylized Z throughout the site to support the theme created by the 'Z' logo.

Anyways, We really need a professional, crisp, catchy logo to put on the new site and something (...the artist formerly known as prince like) that can be effectively applied throughout various media to brand our company. I realize that explanation might be bit 'out there', but if you get that, we are looking for you!
