Two sets of banners, each set different design!
On set is the following sizes:
336 x 280
300 x 250
120 x 600
468 x 60
160 x 600
728 x 90
Design should be light, meaning relatively small file size.
The banners must also be delivered in PSD files and all the text must be editable.
As mentioned already, work should be done very fast! The reason for that is I need to know you're capable of delivering quality work in no time and can make edits very quick (if necessary).
