Customer Database with plugin

PLEASE READ BEFORE BIDDING! Payment after the project is completed. Show me your skills. I sell scripts. That is all I do. I need a customer database for my script store. The customer database must have the following: I want a simple script easy to install and modify with beautiful design and friendly interface. Administrator must be able to edit, add, and remove information easily. Search Customer Search customer by Last name, First name, or Doc #. List of Fields are: First Name MI Last Name Address Address City State Zip Code Country Phone Fax Alt. Phone Email Doc # Remarks It shows the list of customers arranged by last name in alphabetical order. The administrator panel will have two TABS: Customers and Finance. I have a script where admin can track income and expenses. The original script was created as stand alone then converted into a plugin for my website that was using Joovili. Now you have to plug it into the customer database and place it under the FINANCE tab. The tabs must be in AJAX. I will send you this script by email when part of the customer database is completed. The administrator can create staff members whom will help adding and editing customers. administrator can grant staffs different levels of administration. Admin can also create other admins with full right. the script must be secured with no php or mysql injections. Bugs free. PHP, MySQl, and AJAX. You must provide installation documentation, documentation for modifying the design, and how the script works. Do not copy from other website because is a violation of copyrights laws and I do not want any proble with the law. Original work please.
