Need 8 banners, 1200x628 px, for advertising android app

I need 8 different banners, each for a different theme on promoting the Android app.

These banners will need to appear professional yet "POPS" out at visitors when they see it on their newsfeed.

Facebook advertising very competitive, need good banner designs. Thus I need quality similar to the following screenshot. click on link to see.


Hope to receive good quotes, will employ for long term to push 30+ banners if rates / quality is reasonable.

Please provide portfolio.
