A simple mobile salesman application

We need a senior iPhone developer to write a simple iPhone / iPad application for us. We have a CRM system which allows our salesforce to do their work more efficiently, covering presales processes, activities, view/edit customer details etc. This application however is too complicated to be viewed on a limited size screen, such as the iPhone or even iPad. Therefore we'd like to have an application that can display a limited amount of data with some minor actions possible (view and confirm a task, view customer details). The application should communicate via mobile internet, connecting to a webservice open on our CRM system. Our preliminary estimation of the effort involved is between 5 and 7 mandays. More detailed description of the task is available in the attached document, if you need more info - please contact us.
