It is easy to find a computer forensic expert, special master, or a private investigator.  Each of these are great assets in their own right. The true value is finding someone who is a skilled and experienced investigator, as well as a computer forensics expert.  These combined skills make the ultimate combination when the stakes are high and all the facts have to be determined.

Most clients just want to know what is on the computer.  To save costs we start with a Basic Report offered at a flat rate.

What is in a Basic Forensics Report?

It is an interactive and detailed report of the activity on this computer. This report includes any recovered web-based email (Yahoo, Gmail, Hotmail, etc.), Internet History and Searches, Facebook posts and chats, Skype messages and other Internet activity that can be recovered from the hard drive as well as a list of documents opened by the user. 

The rates for a Basic Report are;

$2,000 for any hard drive up to 1 terabyte.

$2,500 for any hard drive over 1 terabyte. These rates do not cover a forensic examination.


Standard cell phone forensics typically comes in two different flavors. Logical extractions and physical extractions. A logical extraction is the extraction of all of the information found on the operating system. A physical extraction is all of the data found on the operating system for any given device as well as the unallocated space often providing deleted files.

A Forensic Examination Can Retrieve:

·  Text Messages

·  SMS Messages

·  Call Records; Dialed/ Received/ Times/ Duration

·  Pics & Graphics

·  Video

·  Contact Names & Phone Numbers

·  Address Book

·  Email Addresses

·  Caller ID

·  GPS Locations

·  Other Deleted Data

Most clients just want to see what was on the cell phone.  To save costs we start with a basic report offered at a flat rate.
