I am creating a site from scratch - the site will allow users to (i) register details of something they own and (ii) using a unique reference number, allow experts to identify the owners of specific items. The site needs to have the ability to (i) record initial ownership with various input fields (including 1-2 file attachments as proof of ownership) (ii) have a system for transferring ownership, whereby a new owner puts in the details and a confirmation request is sent to the earlier owner (iii) there should be an option to mark the item as lost with a potential reward offered and (iv) using the unique identifier number, other users need to have a way of identifying and communicating with the current owner. At the same time there should be an app for both Android and iOS - this can be primarily a web interface with the website but needs to be able to generate notifications.
Can you please share the detailed doc or Wireframes/Mockups? Please Message me to discuss more details for requirements. Kind Regards Champian
