I need somebody to develop a website for me ,I need a developer who can help me establish,design and program.I need a website to be interactive, programmed to calculate the students' scores and provide them with feedback ( in a generated email sent to the registered visitors).

Each test is composed of 50-60 multiple choice questions. The service I offer is assessing visitors/students foreign language ability for free. Hoping to have high level of traffic that may allow me to communicate with later. - I also need a program that calculate the visitors test scores and give final results with pre-written recommendation.
