Clone Site like SparkPeople.com

I need a clone site that does similar things to [login to view URL] (however only require some of what they have, and it will need to be customisable to our products) This site will provide the template for a main health website however I also want the capacity for it to be customised specifically for certain health ailments eg for diabetes. I have a range of health websites that are currently not interlinked and this clone site will provide a basis to integrate all of the generic health and wellbeing tips into one site. Full details of requirements will be given to the person awarded the project. You will need to have both designers and programmers working for you. Great quick project for the right team!
