Google image ads needed

Hi,

We need a set of rotating grapgics created for Google image ads.

We want to keep it simple but there must be:
1. Strong CTA button.
2. Our logo presence.
3. Rotating copy which we can supply.
4. Product graphic.

Each ad must be under 50KB in the following sizes:
Formats: gif, jpg, png, swf
300 x 50 - Mobile leaderboard
468 x 60 - Banner
728 x 90 - Leaderboard
250 x 250 - Square
200 x 200 - Small square
336 x 280 - Large rectangle
300 x 250 - Inline rectangle
120 x 600 - Skyscraper
160 x 600 - Wide skyscraper

We are more than happy to supply extra info once bids are in.
