Php development for our joomla site

We use Dezrez property management system.

The system provides a live search of our properties for our website. The search consists of a standard HTML form containing search criteria which is submitted to the dezrez servers using a standard HTTP POST. A HTML page of search results which match the criteria is then produced by our servers and returned to us. Clicking on each property will submit another query to dezrez servers which will return a second HTML page containing the full details of the property.
