Web App (Email Scraper) - create minimum viable product

Hello! I'm looking to build a simple 4 page MVP (minimum viable product) for a new startup. It will work as follows: 1.) User enters search terms & can choose to scrape emails from Twitter, Facebook, Search Engines, Instagram or All from a dropdown. 2.) After user has entered their search term and selected the search location (Twitter, Facebook, Search Engines, Instagram or All), the web app will scrape the website for emails related to the search term (need your suggestions for the best ways to do this). 3.) These results are displayed in a table. The table should display the name of the person (if applicable), and their email. The user can then remove emails and download the CSV. 80 results displayed per page. That's it. Keeping it super simple. I will provide the front-end HTML/CSS/Javascript layout files, you just need to do the backend (with some form of admin for viewing users). This needs to be SECURE and easy to scale. Code should be clean and selected freelancers must have prior experience of building web apps. Pages: 1.) Home page 2.) Step 1 (search box + dropdown) 3.) Step 2 (results displayed, download CSV & remove entries) 4.) Signup page (take email + password) No login is required, but I would like to restrict access to the tool with a password overlay that I can give to MVP testers to test the general functionality. Please bid accordingly, looking to start this weekend. Thanks!
