Build a Website

i want to develop a complete internet based platform where any individual share their service/goods/any product not in use or underutilized on exchange or sharing basis to other individual. this website will act as a social media platform to bring people together for sharing anything but not selling. initially i am expecting below functionality --user will login. initially every new users will be given 1000 points as joining bonus for starting there sharing journey on the platform. they can even refer and earn the points --should have option to list down items for sharing purpose on the platform --once item is shared an algorithem should valuate the shared product based on criteria like its usability/duration already used/quality/usability and label the product with some points which will be needed by other user to use it (algorithm need to be suggested by the developer) -- once any other user decide to consume a product he need to have points available in his account relative to the product he wants to use --finally when product is used by any other user equivalent points need to be deducted from the consumer account and added to the user account whose product is used --when user decide to consume any product he will be allowed to view the contact of other individual (maximum 3 contacts can be viewed by one user). if user wants to view more contacts he need to pay rs 10 per contacts to the platform --based on the feedback/nature/quality of the shared items users will ranked for there sharing habbits and will be provided some points from the platform only serious developer contact, i need full time developer for a quality product. if quality and expectation are met money should not be the constraint
