HPHP experts,

I'm in the process of setting up a small film production company and I'm planning to install a web-based groupware package. I was wondering if any of you clever people could recommend a good groupware package, please?
I'd like:
- the ability to swap files (scripts, schedules, budgets etc)
- basic project management
- calendar
- contacts
- to-do lists
- wiki
- a media gallery would be excellent (photos, audio, movies)

My friend recommend a website which can find PHP groupware project, but  which one is suitable for me?

Any suggestion/

Thank you for your reply!

Best regards!
Anny!
