I have a customized module for drupal 6 that was created a long ago. It is a questionnaire, that can be seen here: [url removed, login to view] (need to creat an account) It is a simple questionnaire that calculates a result and presents the result to the user.
I cannot show the source code before accepting a bid.
Who accepts the work accepts that the source code should never be published or used elsewhere. And accepts the confidentiality term. Additional Project
The current module should work on drupal 7 (last version)
