Mobile development -- 3

I need an Android app. I would like it designed and built. This application is connecting between peoples that want to give food (for poor people) and poor people.. In the application you can upload "giving" by small decription, photo, contact info and schedule of yourself, expired date etc.. when "giving" uploaded - anyone of the app users can see it and request taking, adding or helping. There is screens: 1. Home: feeds of all the giving list, can sort them by dates, by places in the world.. any feed include picture and small description. 2. Upload "giving": uploading new giving - include the details that mentioned above. 3. History: screen that show all the Deals that was finished with comments of the peoples.. There is many others actions: 1. While clicking on Giving you can request talk with the contact man, [login to view URL] request help.. 2. After accepting of the contact man supposed to maked connection between the peoples (to be writed in the Giving that X did a Deal with Y) - after they finish the app supposed to show each one of them rating of the Deal.. how much it was help you, how was the conact man etc.. 3. All the conacts info supposed to be without or with names as the [login to view URL] the user.
