Looking for an experienced Development Team for a multi-sit

We are an online business design agency that are looking for a development team to develop a number of interactive web applications for us. Each of the projects below are closely related to one another and upon signing a NDA we will disclose further details of this project: 1.) An online business application that has a number of forms that visitors can fill out and get results based on the data they input. 2.) An online database/application where one set of people can post “problems” and another set of people can propose “solutions” with an option for private workspace enabling any two people to work together within the website. 2a.) A reputation management system for the database above that assigns “points” to users of the website based on the information they provide (e.g. phone number, social sign-on from their social networking accounts, etc.) and the activity they do on the site (e.g. feedback, post solutions, etc.). 3.) A standard ecommerce + shopping cart system setup on a website to allow sales to be processed and content to be delivered after successful confirmation of payment. All of the sites in the system will need to be tied together into a “single log on” / “single sign on” system so that if a visitor to one of the websites registers his details, he will not have to register again on the other website in our group of websites. The same username and password would be valid across all sites for that visitor.
