Hey there rets85,
I've been building ad banners for over a decade and it still butters my bread. You can see all my work on my now outdated website when you like: mediagarbage.com - just go to the portfolio and click on any of the ad tiles there you can see my work. I am fast, easy to communicate with, I use native methods and not plugins, and I am familiar with all the different media serving platforms like Doubleclick Studio and Sizmek etc. I currently handle all of the digital display work for Sotheby's International Realty globally as well as all of PBS programming domestically and in England. I really like the work you showed as an example and would be interested to take that project on. I already know pretty much how I would tackle it. I will email you directly about my quote. Thank you!
