Hello Mark,
First of all, the car profiling app description is complete and very understandable, thank you.
The application is applicable and will be excellent implementation, since we have already big experience in iOS specially in iPad; but you didnt mention if you want it Retina display or not, the price included the Retina ready already, so dont worry.
I will be available at anytime you want to call and contact with any method.
P.S: forgot to mention, that this type of apps doesn't require more than 10 working days if the developer is free of projects, its simple and straight forward. I would love to hear back from you whether you choose me or another freelancer.
Cheers,
Omar
