I would like to hire a Software Developer

Looking for a Codeigniter developer who can change the source code of perfex-open source crm from codecanyon. --------------- Perfex CRM is a an open-source CRM with many great features. But, when comes to user-role permission, they have only Global and Local Role permission. I have contacted them and they have advised me to take the help of a developer -- I want a Codeigniter Developer who can modify their source code user role permission so I can have multi-level organizational hierarchy feature like this from zoho. [login to view URL] ------------ In detailed explanation, the CRM provides only global or local user permission settings where-in a person can either see his data or all the data of all people I have 4 Levels hierarchy in my organization with the Level 4 being the persons from sales department who will directly call the client and record data in CRM fields about the client. With User Roles ( I can edit him to see only the clients data that he has filled and not others as per my understanding of documentation) My use case is: —> Under each Level 3 person, there are 10 sales persons. —> Each Level-2 manager has 10 Level-3 advisors in his team (So he has around 100 Level-4 sales person to manage indirectly ). —> And The Level 1 is the CEO who manages everything and has around 5 Level-2 persons in his team My Doubt is: Can I configure the user role in such a way that Level-3 person can see the leads generated only by his level-4 sales team? and Level-2 can see the leads generated in all of his Level-3 teams only And Level-1 (The Admin role) can see all the roles? ------ So, I need a customization where This user level hierarchy can be done instead of only global or local customization over there. The customization is even explained in the image attached.
