Development of an APP for classified ads so that users can buy and sell cars and motorcycles

I’m looking to commission a talented freelancer to develop a custom app that facilitates the buying and selling of cars and motorcycles. The app will need to be developed for both iOS and Android. The successful freelancer will need to include a detailed project proposal in their application, as well as demonstrate that they have the skills and experience to successfully complete the project. I have a specific design in mind for the app, so in addition to the development of the app, there will be a design component to the project. I attach a PDF file with the terms of reference, explained in detail, if you have any questions just let me know

I need the source code of the APP


Thank you so much.
Hope we can work together!
