New Website with Assistance of my VB Program Flow

The website needs to be built with the functions, buttons and operational design in the VisualBasic Demo I created. My Program is not fully functional so I will also include text to explain some of the function details. The demo will help entirely with the speed and understanding of the flow and design functionality. I have created a list of the name-fields needed to assist in the database creation; I have probably completed about 90% of the database field list with an exception to some that you may need for connection to the database. The website must allow for customers to register, companies to register, admin to log-in. The website needs to provide each company with their own webpage, dashboard and appointment booking system. The website for each provider would be [login to view URL] The customers need the ability to add their chosen companies to their webpage for easy access to them and to be able to interact with transactions specific to them. There must be a simple settings section for each company so they may change certain parts of the background frame colors or upload their own backgrounds and a banner and a few picture frames that they can populate; the page fields/forms will all be the same and not editable but there will be picture fields that are invisible unless used. There is also a question form section that needs to be able to be filled out by customers of the companies, each company will have the ability to choose their own (yes/no) questions and create their form. Each company should be able to edit/add/remove their own form questions. There will also have to be a simple transaction view and print section for customers and companies; each. There will be future expansions of this project and I would hope to be able to use the same web development company. The website does NOT need to be able to take credit card payments at this time; but it needs to have an accounting system that allows admin to charge/credit on account. The companies will need the ability to charge/credit on account also. Please feel free to request more detail if necessary.
