I'm working on a drupal project that collects information about a business and then offers advice based on the information submitted.

Following the initial sign up process, a user can add a new business profile content type. This will be the entity referenced by all other nodes related to this entity aka the "business profile". Based on the answers provided within this initial questionnaire, I want to require the user to complete other supplemental questionnaires (basically other content types with entity reference to the main business profile content type) before submitting a finalized business profile.

For example, in the initial business profile there may be the question "Do you have any foreign operations?", if the user answer yes, I would want to make them complete the "foreign operations" content type questionnaire with many fields that relate to foreign operations. Further, if the user answers no to a question such as "do you have any employees?" I don't want to make the user complete an extended questionnaire (aka an employee related content type) regarding employees. In addition to simple yes/no answers, if a user selected a certain business industry SIC code from a select list, I would want to require specific content types to be completed with questions related to this industry. In my mind, I could have 50 content types with questions, but for each business's unique operations, they may only need to complete 5 of those content types. Finally, I would need a dashboard to keep track of what content types are required, pending and have been completed - then once all of the required supplemental content type questionnaires are verified completed, allow the user to submit a finalized profile.

I would say my level of drupal is intermediate as I understand the basics of entity referencing, structure and views; however, admittedly my experience in rules is limited. I'm using drupal 7.x.

I'm hoping someone can help to offer me a rough step by step of how best to accomplish this. (i.e. use this module, within rules conditions add blah, etc. etc.) Is my approach the correct one or is there a better solution such as webform, etc.?

Any help or guidance is appreciated.
