Cursor Ai Expert for WordPress Plugin Modification

I need person with Cursor Ai to modify my existing plugin. My previous developer could not finish it. I want someone with experience of Cursor Ai.

My WordPress plugin is a client portal, and here are my list:
-In Portal setting there is a "Feature Control Center" and they all work I've tested except for two Add Ons are unaffected and if you can find the setting and put it to what I set to
-Ticket Support doesn't work at all
-Can't create project and make sure you use date picker - missing in updated plugin
-Can't Create task and make sure you pick date picker - missing in updated plugin
-file manager based on whmcs plan of Web space (not random number)
-Forms should have sort by clients - not completed
-Appointment/Bookiing I want full version booking/appointment with shortcode
- each tab inside website has Briefbuilder and will save in each section
-Domain name I can type anything like fdsjfdsfdfdfd.fdsfdsfs and it will say available while networksolutions.com says not available (check image) this make no sense. It has to be available based on what I checked and so far I have checked only few extension. Can you tell me what is exactly I need to do.

Affordable rates only that's why I'm asking Ai,
