Website creation for NGO with Integrated Payment System

I am looking for a skilled web developer to create a high user-friendly, dynamic website with modern and minimalistic design, for a fundraising foundation. The website should be more than just a place to fundraise money, it should allow users to log in and create their own fundraising campaigns or donate seamlessly money to other people campaigns. It should be integrated with a platform that offers translation for multiple languages (Starting languages: Spanish, English and German), it should offer a seamless and pleasurable fund-raising experience, and it should be built in a way that the owner does not need to understanding website developing to maintain it and can easily modify content and images. The key elements of the website include: Key features that we would like the website to include are a photo/video gallery, a donation button for fundraising purposes and an event calendar to promote upcoming events. Integrated Payment System: The website should feature a robust and secure payment system. It should allow users to quickly and safely make payments using various options, including credit/debit card payments, Apple Pay, and Google Pay. User Interface and Experience (UI/UX): The website should have a clean, appealing, and intuitive user interface. It should be optimised for both desktop and mobile users (Web 3.0). Security: With the integrated payment system, the website's security is of utmost importance. It should adhere to the latest security standards and regulations to protect users' data and transactions. The ideal candidate will have experience in web development, UI/UX design, and payment gateway integration. Knowledge of the latest web development technologies and practices, as well as a strong understanding of security standards, is crucial. If you believe you're the right fit for this project, please provide a proposal outlining how you'd approach the task, along with samples of your previous work. Please be very explicit in your proposal, attach an initial draft sketch and confirm what would be included for the draft, and what would you need from to make it happen. Additionally, please confirm what is not included but could or should be done and how much it would cost.
