Modify a dashboard in php and ajax

I need someone who can help me add some features to a web based system to monitor employees activity like screenshots, mouse and keyboard activity, active apps, active windows, visited websites, etc. The system generates and displays charts based on [login to view URL] and most interactions with the system are in ajax. Most of the system is also based on wordpress installations. Some of the changes I need: 1. Make queries on dashboard more efficient since it takes too long to load/process 2. Add some other filters to the work diary 3. Each employee in the system has a set of "personal keywords" like [login to view URL], [login to view URL], [login to view URL], etc which are compare with active window title and browser url to determine if activity is personal or work. I need to enable the system to add keywords that applies for all employees. 4. I need to enable the system to work in different time zones. And several other updates that could lead to negotiate an steady income since I need someone to maintain it so I can provide support to users. All activity of computers are stored in mysql database and are gathered by .net application installed on computers Queries to generate charts and stats are complex so I need someone with good logics and programming skills Find attached a few screenshots of the system that might help get a broad idea of what needs to be done Price for each updated or group of fixes to be negotiated with candidates, I will first ask for one update and if done then we continue with the others. Please only bid if you have the skills to do them all, not just one... I need a reliable and always available person that can learn the system and make updated when needed. Budget set in project is meant per updated not for all of them of course... Thanks!
