See attached document for a possible wireframe example.
Remember the wireframe is just a starting point, feel free to use it or use your creativity and go in your own direction. I'm just showing you what llinks we need.
Colour guidelines: tend to stick to blacks, reds, purple, silver, bright neon pinks etc (avoid Pastels, brown and boring stuff)
Fonts guidelines: Horror/jagged/tattoo/scroll type fonts are always good
Icon guidelines: skulls, stars...tattoo type things(think ed hardy stuff) pin up girls, razor blades, cherries, guitars...
Backgrounds: Like detailed backgrounds etc
Boxes / categories: We like it when they have a generic feel but are all a bit different with slightly different backgrounds etc rather than just a box with the word sale in etc.
Use a combination of your own images and images from the current site or stock image websites which you modify to create a uniform look. We are happy to buy a few images.
For manufacturer / brands logos use some from this page: http://www.classixshop.com/acatalog/brands.php
See the attached file for images from istock which the clients like to give you inspiration. Feel free to use the images or to find other similar images.
