iPhone 2.0 App

I am looking for an iPhone Apps developer who can put together a secure online database: The following data will need to be entered or collected: First Name, Last Name, Address, City, State, Zip, Phone. This will track contacts and what was given to them and when, so we need this to have some fields for date, what was left with them, and notes for next visit with them. It would be great if we could also show on a map all the contacts in this database, near the area the user's current location (using the GPS map feature). It would be great to receive a monthly summary also of how many of each of several items were left with all the contacts (to track inventory handed out for the month) The information collected needs to be able to be searched through using the iPhone. It would need a secure login and I would need admin rights to set up accounts for access and to be able to delete any records. The app would would need to take advantage of the iPhone 3G GPS and be able to pinpoint where and when the information was submitted from. The search features would have to take advantage of the Google Maps application on the iphone. If this can't be done as an iphone app, I'd like to do it as a web database that can be used from any phone.
