메모 기능 웹사이트 구축

Hello! I am planning to develop a simple website with the following features, and my budget is around $100. Please let me know if this is feasible to create: As soon as users access the website, they can log in with their ID and password to immediately see their saved content. Users can convert their notes into "PDF or JPG" format quickly, which will then be saved to their phone's photo library or their computer's download folder. When making notes, if users type "@" followed by a word, a corresponding image will automatically be inserted into the document. There will be multiple templates available for use. Users only need to enter their ID and password to register. Users' records will be encrypted with five layers of security to ensure that they are completely private. Biometric authentication (using fingerprints, facial recognition, etc.) will allow users to access their account without needing to enter their ID or password. Users can store up to 100MB of files in their folder. Relevant advertisements will appear at the bottom of the memo website, aimed at increasing purchase rates. Another section of the website will explain why users should choose this website. In the "WHY US" section, the website's color scheme will change as the user scrolls down. The website will feature a live chat function to immediately address any inquiries or suggestions regarding the website. The "password save feature" on the website will include a specific format for storing passwords (e.g., password entry field, website URL field), and this sensitive information will be encrypted multiple times to prevent leakage, even in the event of a hack.
