Creating my own billing credits

For my own billing I have made sure I complete the billing in the same order which a normal thriller billing is in.

This is the billing me and my group have made:

The order I used was:
1. Production companies
2. Directors
3. Main actors names
4. Music/Composer of music
5. Editor
6. Casting director
7. Production designer
8. Costume designer
9. Director of photography
10. Executive producers
11. More producers
12. The novel writer
13. Script Writer
14. Director
