30 Small Banners

We are in need of 30 small (150x150) banners which we will rotate on our website. We will provide the necessary text, you will provide the graphical skill, creativity and inventiveness to make sure that they are noticed on our pages. All banners will be static, and their file sizes must be optimized for web use. The theme of the website is "occult", so you must be confident that you can design all 30 to be eye-catching, individual (no 2 the same), yet still fit into the theme without being corny (no witch hats or brooms or cauldrons, etc). Any banners that we feel are unsuitable shall be returned for redesign until we are satisfied. Payment will be 100% by escrow, released only when the work is complete and delivered.
