iPhone App - Product services and warranty renewals

I wish to have an iPhone app made with the following features: Login checks an existing database Customer details returned and app stores all products the customer has pulled from a second database Than all services or warranties a customer has for each product is pulled and stored on app this info coming from a third database Also need to enable push messages and notifications so when a warranty is about to expire e.g. 3 months prior a notification for renewal is sent. Need mailto and intiate calls function, using geo-location so if the user is in Germany the call is directed to our German centre, if in UK irected there Also need assistance in adding a nice graphical interface to the app. All databases are provided but will need to set a mobile server up to store all there as all 3 databases are coming from different locations and will need to be stored in one place for the apps use. I have attached slides of my initial idea, please PM me if you have any further questions.
