business directory page

Hello, this is a request for proposal. We need a page on our website where companies can self-register and their company information auto appear on a page on a webpage with in our website. For register companies, this would be a registration form which auto publishes to a page where website visitors can view the information (Basically a directory ( list) of companies and their information). On the back in the company registering can make as unique log-in so that if they needs to change/update their information they can do so at any time. It would also have an admin role so if we needed to remove anyone who has registered from the directory, we can easily remove them. On the front end (directory page) viewers can sort alphabetically, search by category, or key word. Default setting all listed companies would be collapsed, with the ability to expand to view all their details The would directory would be embedded in to my website as new page. the website site is: [login to view URL] Or you could create an HTML into my website that pulls the data from a data and displays it properly. (this may be easier). I am looking for someone with experience. If you do not have experience in doing this, please do not reply. I will be looking for live examples of your previous work. Proposal must include the following: Proposed design approach proposed architecture proposed programming language indicate any third party platforms and any licensing requirements Ability to transfer all source files Project timeline Estimated cost Availability to start ONLY formal responses will be accepted. Those wishing to respond must submit a proposal in PDF format for consideration. Do not message unless you have a specific question.
