What tracker is best used when the following requirements?

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
  1. The number of users to 20 + superadmin only
  2. Division of roles (Manager, worker) rights
  3. The opportunity to share the projects to certain users
  4. The ability for each user to choose his interface language
  5. Total customization of the interface for employees
  6. Email + sms notification
  7. The division of ticket statuses (task, test, completed, bug)
  8. Assigning tickets
  9. Choice of ticket, from among unassigned
  10. The number of hours for the implementation of the ticket
  11. The ability to specify the value of the hours separately for each employee
  12. Statistics for users and projects
  13. Attache for each ticket + the discussion in trello
  14. Checklists for each ticket in trello

Wishes

  1. The ability to specify the cost of the project
  2. The ability to put a fix rate for employees for each ticket / project as a whole
  3. Half-tracker out of the box / connecting third-party time-tracker
  4. Connecting git / github repositories with an indication of commit for the ticket
  5. Chat with the logs
  6. Notification system for employees (different information, holiday greetings, notifications by the system)
  7. 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?

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

There is a good service Deskun, with the help of it you can implement almost everything that is written in the requirements. Works inside Google mail is that for me - very comfortable and adds a lot of pluses. I suggest you look.
