Banner for Product Promo

I need a single 300 × 200 px web banner that instantly promotes my product/service. The look must be bold and eye-catching, with strong colours, clear typography, and just enough negative space to keep the message readable at a glance.

Here is what will help us move quickly:
• I will provide the product name, short tagline, brand colours, and any mandatory logo files as soon as we start.
• You can suggest whether a product shot, an icon, or pure typographic treatment will work best—whichever sells the offer most effectively at this compact size.
• Please create the artwork in Photoshop or Illustrator and supply the layered source file along with a web-ready PNG/JPG.
• Two initial concepts and up to three rounds of tweaks should be plenty for us to lock the final version.

A punchy 300 × 200 that drives clicks is all I’m after—if bold design is your thing, this will be a quick win for both of us.
