Customer database

GAFers, I have a database that I need to track customers. It will be our in-house Customer Relationship Management (CRM) Tool to track customer prospects and orders. It needs to be secure and unhackable. There are about 50 fields of information for each customer ranging from name and email to value of order to product photo. Date fields need to include text, dates, image files, pdf, functions to display information. Only 10-20 fields will ever be displayed. I want the views and other info be available to be defined through an admin panel. The user interface for both admin and users needs to be pleasant to look at and not just blocks and rows of data. I want it to look nice and be easy to read. Please refer attachment for details on fields. -Tony
