Website prototype and building

I have following website in mind for education purpose. I am looking for UX/navigation prototype, and actual building of the website ( and iphone/android apps) as the follow up project. But to start of I am looking for the webUX/prototype as the first step.

High level Requirements:
The website should have typical pages like signup(parent), login(parent and kids), and page for listing courses, and page which hosts each of the course. ( for this example lets consider two courses).
The home page should contain the about and intro about the website, reviews in the bottom, the list of courses offered with subsciption details ( example free trial ) etc, There should be two logins supported.
1. Parent login should be able to add kids login, enter payment details for the course they are enrolling in.
2. Parent should be able to see what courses each child has enrolled, completed, scores/rewards they earned overall, and any other notes about the kids.
3. Kid login should land at home page which provides them list of courses, and overall score/rewards they have earned at top of the page.
4. once kid chooses course, the course page should host the following elements.
a. starting video that provides intro video about the course.
b. second video that provides the actual content of the course.
c. component to host picture/video based quiz i.e in addition to the text content in question and multiple choice answers, there will be picture/video associated with it.
d. once the kid answers it, there will be immediate feedback, so kid can learn what is correct.
e. component to host a simple game to make the learning fun.

I am looking for example websites you have built so far, so I can look at what kind of projects you have worked previously. Once we agree mutually, I would be happy to discuss more details about the requirements.
