The problem
Are in a situation when the number of tasks on current projects and number of potential projects has increased to such an extent that it is impossible to keep everything in my beloved todo-service. Need a competent tracker with a number of requirements and wishes.
Please suggest which tracker best fits my needs.
Requirements- The number of users to 20 + superadmin only
- Division of roles (Manager, worker) rights
- The opportunity to share the projects to certain users
- The ability for each user to choose his interface language
- Total customization of the interface for employees
- Email + sms notification
- The division of ticket statuses (task, test, completed, bug)
- Assigning tickets
- Choice of ticket, from among unassigned
- The number of hours for the implementation of the ticket
- The ability to specify the value of the hours separately for each employee
- Statistics for users and projects
- Attache for each ticket + the discussion in trello
- Checklists for each ticket in trello
Wishes- The ability to specify the cost of the project
- The ability to put a fix rate for employees for each ticket / project as a whole
- Half-tracker out of the box / connecting third-party time-tracker
- Connecting git / github repositories with an indication of commit for the ticket
- Chat with the logs
- Notification system for employees (different information, holiday greetings, notifications by the system)
- FREE of charge :)
Summary
Trello good and part of requirements and wishes are implemented with the same zapiram, but I would like a holistic system, which I never really care about. What can you recommend?

Please note, that the claim "FREE" is in section "Requests" and, if possible, to take this into account when replying.
