Design an attractive and professional website banner or header

What the Freelancer needs to start the work

And here's the info I need:
The URL to your site
The DIMENSION in pixel or inch(very important, width by height)
The specific TEXT(including button text if any and the font type if specific font is needed)

Also, if you have any important images i.e. logo, product images, headshot...etc, pls send them as well.
