Cross-Database in Real estate market

Good morning to all the community, We are a marketing agency in Switzerland. We are looking for a developer or a team to develop a small web platform. 1) [login to view URL] This website shows transactions.. but without the address. The address is only a City number + a land number. Exemple : 01.01.2000 - Carouge, 8 - Affaire 2000/3846/0. Héritage. Ancien(s): Brad Pitt, California, inscrit le 23.12.1999. Nouveau(x): Jolie Angelina, Villefontaine, Lausanne, en communauté héréditaire, COP Carouge, 8/2640-2 sur 1/2 du B-F Carouge, 8/2640, 237 m2, Habitation à plusieurs logements (sur plusieurs immeubles), Garage privé (souterrain, sur plusieurs immeubles). 8 = city 2640 = land number 2) To find the correspondence address, maps and directores in open-source are available on this website: [login to view URL] Or directly there when we have the city and land numbers : [login to view URL] Change the = 8, by any City Change the 2640, by any land number 3) Then, the address appear on this previous link! Magic. Our idea is to create a database with cross-database queries automatically. • We upload the new transactions files as in 1) on a database • a “plugin” search automatically the address on 2), extract it, paste it on the ID transaction line. • An advanced toolbar (any words, date (between), price (between), city) could be selected • Display the results on a simple tableau [Removed by Freelancer.com Admin] We will deal only with a serious company/dev with a similar experience and portfolio. Warm regards, Philippe H.
