Adobe Indesign Index Plugin required

I require an Adobe Indesign plugin that will generate an index based on word frequency, proper nouns, subjects of sentences, a list of words and phrases that are supplied, marked items, or any combination thereof. First and last names can be reversed automatically, duplicate entries removed, and a multiple-level index generated. The plugin delivered must work with Adobe Indesign CS2 and CS3. The plugin must be encrypted so the scripts are not open for inspection. The plugin must require a serial number issued from me before anybody using the plugin can run the script. I also need the ability to provide a time limited and/or feature limited demo of the script - e.g only an index for the letter "a" is produced. The plugin must be supplied with documentation including screenshots, and a Camtasia video showing how to install and use the plugin.
