Banner Advert design

Design details: Hi I would like 4 banner adverts designing (the google sizes & a facebook size) for the new patient engine.

To drive people to this page http://unbouncepages.com/newpatientengine/
http://issuu.com/clickconvertsell/docs/the_new_patient_engine

the call to action would be

"How many new dental patients are you missing? Take the New Patient Challenge now!"

This would be 2 images in gif form rotating so having the headline

"How many new dental patients are you missing?

Then

"Take the New Patient Challenge now!"

thanks

Ideas for the visual style: see attached
Extra notes: Style - to target dntists and to look very eye catching and clear like an emergency! How many patients are you losing?
