Custom Survey Set Up

I want to set up a survey system for clients on their site. For the Client I have a system set up where they can create new surveys. Models set up are Survey: has a type and a confirmation message. Question: questions associated to a survey model by id. has columns subject, and answer. The client will give a customer a link to the appropriate survey, what would be a clean way of saving individual answers per customer submission? My thoughts would be to have an answers table, with just the answers saved and related to a customers unique survey_answers_id. Just not sure how to go about this. any suggestions are appreciated.
