Transactional Ad Unit Script / Application

Hello Freelancers! Advertising scripts and applications are largely struggling to engage visitors. That being said, I am looking for your help developing something new and exciting for advertisers to drive visitor engagement. Note: Facebook is a potential starting point for the launch of the script. The goal is to produce native or near native advertising script that when hovered over will lead to a secure lead capture or transaction form. Preferably this would leveraged through in client facing application where they are able to self serve, however a customizable script to be used in-house will be satisfactory if price inhibiting.
