Joe Davis from the response above will build you a fantastic custom Website template via his company i7MEDIA
OR you could do it yourself if you have the skills.
OR you could use Artisteer to create an HTML Website template then follow the directions here to tweak it and make it mojoPortal compatible. You still need minor skills in css to perfect some Artisteer skins.
OR simply choose from the many skins that come with mojoPortal and modify them.
I know. Too many options.
