Joomla Extension Customization for Enhanced Reporting -- 2

I am looking for an experienced Joomla developer to help with modifications to an existing custom Joomla extension used for a time-keeping system. This extension is not overly complex, but it requires specific updates. Here's what I need:

1. New Input Area:

New input area similar to (Alias: time-entry)
• Dropdown called “Type of Escort” with options: Funeral or Load
• input box called Load Number:

• Start Date & Time:
• End Date & Time:
• Total Time (calculated from Start and End):

2. Enhanced Filtering in Admin Reports:

Addition of a filter by “assignment” in the “Entry by User” section of Admin Reports.

3. New Report - “Motorcycle Log By User”:

Ability to export to Excel.
Filters for Name, “Type of Escort”, Month, and Year.
Similar data presentation as the “Entry by User” report.

Pre-Modification Requirements:

Verify that the Joomla file (.zip) I possess matches the version running on the production site.
Perform modifications on the verified version.

Testing and Installation:

Test the modified extension on your own Joomla test site (which I need access to for review).
Assist with installation on my production site.
