Thank you for reaching out to me with your project requirements. Based on your project description, it seems like you need a desktop application or a local file for personal use only. As a highly skilled and experienced developer, I can assist you with this project. However, before moving forward, I have a few technical questions about your project which we can discuss in detail to provide you with the best possible solution and a more accurate timeframe for development.
Regarding the budget, I understand that you are looking to keep it under €50. While this may be feasible for a simple project, my priority is to provide you with a high-quality and efficient solution that meets your requirements. I am open to discussing your project requirements in detail and explaining what is feasible within your budget.
Please let me know if you are interested in proceeding further, and we can schedule a meeting to discuss your project in detail, address any concerns and offer solutions to bring your ideas to life.
