Social Network Expansion

My website is a social network for photographers, models, musicians etc. to post their previous work, post casting calls, to network and get more work. I hired a developer for phase 1 and he completed everything I hired him to do with the [login to view URL] CMS and PHP language and MYSQL database and multiple modules from [login to view URL] I came up with more ideas that he doesnt have the expertise or time to do. I've got 25-30 more things I need to have done to my website before launching. Looking for a reputable capable company that can build the expansion for me. I would like phase 2 to use the codeigniter framework from [login to view URL] This will require customizing some existing source code. I have a detailed plan of everything that needs to be done. Sample of things to be done: My plan is much more detailed and longer. 1. Newsfeed that is similar to Facebook or Modelfy. 2. Members can click a button and the portfolios and comp cards they create will turn into a pdf. 3. Send mutual connection and email to be introduced - a la linked in 4. RSVP an event [login to view URL] module 5. Members to have their own calendar via expression engine module and customization 6. Members photos to appear next to them on the site 7. Wants members to be able to write the blog posts on the main blog Looking to get started right away. Happy holidays, Paul
