Mobile app required for Android and IPhone

I would like to develop an application that ties into an existing database application online, which includes a lists of club members, and downloads the list of club members, including names, addresses and phone numbers, into the cell phone. Users could then click on a phone number to dial it, or on an address to bring up the location within the maps utility within the phone if one exists. I do not have back end access to the online application which hosts the database - they are a separate developer. You must have a proven track record making easy to use elegant apps to be considered for this project. More details will be provided to selected qualified workers.
