Hi!
I specialize in banners (static jpg/png, animated gif and html5).
Do you need 4 differrent banner in one size or do you need 1 banner in 4 sizes?
Share please more details about current project:
What's an idea/storyboard and copy?
Do you have examples of banners what you like (to understand styles, animation, etc)?
What sizes do you need?
What are specifications (GDN, DoubleClick, Sizmek, AdRoll, AdForm etc)?
I can provide link to my profile on Upwork with many positive feedbacks.
I will provide many examples if you need.
Best,
Sergij
