database design, development, implementation for weebsite

I need help working out what help I need. I know what I want to do but not how it can be done or designed. Needs are: - questionnaire on homepage with specific graphic output - to be able to gather and analyse customer needs and requests on website forms - database of suppliers and customer feedback on suppliers First part of the job would be helping me work out the job. Prototype website in weebly, then migrating to wordpress.
