Develop a Robust Church Management System WordPress Plugin

Hello, we need a custom interactive plugin for church that works like Pushpay’s ChurchStaq or Church community builder system and is capable of handling the following features or components for Church:

Church cell/small groups management
Multi-location specific member management
Learning Management similar to Buddyboss
Online Giving/Donation and Account Reconciliation Features
Worship planning
Check-In system for Church such as kids ministry
Event Schedule
Volunteer and staff scheduling
Administration
Growth Process Map
Communication

The purpose is to have a community feature on the Church's WordPress website where users/members can signup for an account, join or be added to a cell group where they can interact, and hold virtual meetings with a simple interface where they can manage their account on the frontend with an admin moderation and management.

The Buddyboss platform group is similar but not close to what we want. We want a group that is specific to Church.

People in the Cell or small groups system should be able to do the following listed below.

1. Join a virtual meeting and be able to interact using tools like chat, add members to the group, invite members to join the group, assign follow-up tasks to cell group leaders.
2. Internal messaging system among group members - the leader of the group should have a tool to communicate with group members on the GO
3. Support Life Events celebration of group members such as Birthdays, Wedding Anniversary, etc.
4. Receive messages and communication from the central office through the Admin channel
5. Simple interface which has very specific tools
6. Be able to integrate a web and mobile app version
7. Multi-lingual capability for global integration
8. Integrate other in-demand or scheduled resources such as Daily Bible Reading, Daily Supernatural Revelations, and daily prayers from the Pastors.
