Math-based Web Game - Javascript - Play in Browser

Seeking a javascript specialist who can help us build a low-tech introduction to math.
We have developed a main character, selectable avatars, backgrounds for different settings and a complete list of questions and formulas that will be referenced throughout the modular game.

As our javascript specialist you will be helping us:

- create user registration pages
- create a login page for existing users
- create the profile interface for users to select their character, choose a name etc
- integrate our excel based data sets (the numbers and figures) into several places (such as a cell phone, laptop and illustrated paper invoices)
- build simple input fields for users to input numbers and receive feedback on correct/incorrect answers or placements of numbers
- simple animations to segue between scenes and settings
- a scoring/feedback system of red, green, orange interface colour changes
- the entire game moves in a linear direction with numbers presented to the user and their reaction/response to the numbers and where they belong
