Maintenance for Social networking site

We have a social network site that has been developed and has been live for 3 months. We have over 700 members. We are looking for someone to maintain the site and make improvements to it. Some of the improvements that need to be made are: - Add new pages for multimedia content - Enable html codes so users can post comments using html codes. We currently have a text editor that does not allow html codes. - Enable online status of users so you can see if a user is online or not - Integrate with yahoo, hotmail address books so users can check if friends are already members Our site features chatrooms, free email with our domain, blogs, romance and party promotions. We are working to add more features for the site. the site is targeted to the Indian community. Prefer to work with developers in teh US as it is easier for us to communicate.
