Paid/Free animated icons download website

We have hundreds of SVG animated icons made in GSAP. We need a website to sell/distribute our icons. Website requirements: - Make in Node.js - Use Browserify for browser JS. The browser JS bundle file should not go beyond 1MB. Please include the required projects carefully. - Innovative design like: [login to view URL] - Database using pure JSON files OR NoSql, should be fast to handle a million users. Should be light on RAM. Please be careful when saving data to JSON files, it should not get corrupted over time OR whole purpose of this App will become useless. Better suggestions about database will be great. - Should be responsive for every device. - Admin interface to manage users, icons, payments, downloads etc. - Our team should be able to upload icons in zip format on Admin interface. - Zip file should be automatically unzipped on server to show icon SVG & animation to end user on website. - The icons list to show on website should be generated automatically, using the uploads. The icons will compulsorily have a .JS animation file in them and so category & other info can be read from them. - Multiple categories/tags for icons on website. Tags are preferred. When a tag is clicked, all related icons should show. - Icons will be either free OR paid. - End users will be able to select icons and they will get gathered in a cart. If there are paid icons in the cart, user will complete the payment first using PayPal or Credit Card. - After payment is fully done, a link will be generated for user to include that in his code in HTML (embed) and so the selected icons will start working on his website. - Once a payment is done for an icon, user should be able to use that icon for as many selections as he wants in future. - User's icon selections/downloads should be saved under his account to be accessed by him later. - User should be able to name his selection as his project name. For example he can select 4 icons for project X, 7 icons for project Y and so on and the info will be saved in his account with an embed link for his HTML code. - Meta should be added properly for SEO. - Analytics (Google) - User login should be PIN based which will be sent to his email. No password system needed. Please feel free to let me know of any questions. Please bid only if you can do it seriously. ***Code that you send to me, will be a full copyright of my company. ***You should not be able to sell the code elsewhere to anyone else. Cheer!
