Banners needed

We need various size banners designed. All banners should be eye catching, with some rotating layers (not static) in gif format. Banners should pass size (kb) standards. We devided banners to groups: group1: Skyscraper (120 x 600 pixel) and Wide Skyscraper (160 x 600 pixel group2: Rectangle (180 x 150 pixel) and Square Button (125 x 125 pixel) group3: Full Banner (468 x 60 pixel) and Half Banner (234 x 60 pixel) group4: Leaderboard (728 x 90 pixel) Banners in group are differ only by size. So basicly, need create 4 unique banners. Our budget is tight (15$ per banner), but work can become ongoing. You should have good experience in creating eye catching multimedia banners. Please PM me with samples of your previous done banners.
