Users and Galleries possible like in www.oxp.de?

I look for a system like the website www.oxp.de with
userprofiles and galleries of this user?

User Functions:
- Userprofile
- Guestbook
- (many)gallieries
- Fee for more space for the account

Gallery Functions:
- many Galleries per user
- access restriction

Picture Functions:
- Comments
- Ratings

exists some extensions and mods to get this functions with G2?
or some mods planned or in development?

or somebody know a existing system like this? or somebody give me a hint where i can search for this?

thank you for your response.
