We have a real es´tate website where realtors has to upload all their properites themselves.
We have found out that realtors are very lazy and we therefore think if it was possible to develop a type of add on or code or something which allows our site to take the information from their existing website. I understand them when they have more than 500 properties that they don't have the time to sit and upload these to another site also.
Only answer if you also can provide a short description about how you will get this to work. Our main site is programmed in PHP.
