Community Network Profile

I am using a dolphin community software, but need someone to do some custom work. The friends request on it basically just adds a member to someone's friend's list without approval. I would like to have this changed, similar to the popular myspace, friendster, where the member would have to approve or deny a friends request. Also, I would like to have the friend's request, all the comment's by other members to video, profile, photo's etc. be emailed as a notification to the member receiving the request and comments. I would also like to have friend's profile updates be an email notification to the friends of the member who updates their profile. All of these things are something that friendster and myspace already have. I need this added to my site. Please let me know if you can do this. I would like this done fast.
