Hello,
I am a programmer and designer and I am a huge fan of such "brain-teasing" apps and pages, so it would be a very nice project and challenge to do this one.
However, I have some questions:
1. Will you provide the tests, or will I have to design/provide them myself
2. Do you have a corporate identity already?
3. Are you thinking about a web-based project, or an app for a tablet, for example?
4. How is your time frame for this project.
5. What is your target market? Small children? Teenagers? Young adults?
I didn't place a real price on the bid, since I would like to know more about the project to give a better cost estimation and delivery time.
I hope to hear from you,
Sincerely,
CR
