Wordpress Import / Export Software

We are a real estate agency and are looking for a programmer who can program the following system for us. To display real estate offers on our website, we use a Wordpress page with a database on our own VServer. We are connected to a real estate network where approximately 70 real estate agents can advertise their real estate and each broker has their own agent page of only the property of the respective broker to see. Import: We need a WordPress function which allows us to import only the objects of the individual broker, including all the data and photos, into our database. To determine the individual broker, the import should work through the broker's URL. Example: "Mike" has 100 properties on its own brokerage site, the broker side looks like this: [login to view URL] Now we want to enter the pages URL of "Mike" in the Wordpress system and all 100 offers from Mike are imported into our database and displayed on our website. Like a Scraper. We work with XML feeds, which we import via the plug-in "WP All Import", this plugin could be rewritten so that it not only works with XML URL feeds, but also with normal URLs. Or you can automatically format an XML URL from the "Mike" URL, which we can import via "WP All Import". The remaining steps, such as the mapping, are included. Export: In addition, we need an export function, which exports the objects from our website to our partner portals, we currently have only one partner portal, you get a detailed interface description to program the export interface. For the export, a plugin or program should be written in Wordpress, whereby we can determine which offers we export to our partner portals. You will receive from us all the documents you need, we would like to do all this in 2 weeks and will be billed at a fixed price.
