Twitter and Facebook Mods for SocialEngine Community

I am looking to have custom developed Twitter and Facebook Mods for SocialEngine where users can auto-login as well as login via an icon into my Social Network using their Twitter or Facebook credentials. They should then be able to invite friends from both sites, update their status on both sites, connect with the community members who have a Twitter and Facebook account, and tweet and post messages to both sites. The Mod also should be developed in such a way that other features of the site can take advantage of the Twitter and Facebook integration capabilities.
