BuddyPress.org

Sorry if this is the wrong spot, I’m not quite sure where to put this.

I am looking for some specific functionality that I am not finding in plugins. It is not for an existing site but one we would like to build. We were hoping that buddypress would be a good platform for the site but I’m not quite sure.

What we need is somewhat similar to pinterest.

Required functions:
-each user would have multiple pinboards
-user could set privacy of each board – only me, friends, show to everyone
-each item on the board would have an image, short description, maybe a price
-each item would have checkboxes or comments that only friends could see and use but not the user actually owning the pin board
-each user has specific friends, not just groups (I assume Buddypress already has this but I haven’t used it much)

Other functions that would be nice but not necessary right out of the gate:
-tags or categories for each pinboard
-way for people to see list of items from boards that fit certain tags or categories
-targeted advertising based on tags or categories

I am assuming this probably needs some kind of custom plugin build. I am definitely not a programmer so if anyone has ideas on how to implement this, how long it might take to build or how much that might cost, I would sincerely appreciate it.
