Special search engine
Read requirements very good please:
Example how system must work:
I know that soon by a real estate company a house will come in sale, but I have to wait before I can react on that house (because it is not there yet), and because I am interested I want to have it.
What I can do is sitting day and night before the computer, before I can react, but that doesn't work.
So that why we want a 'search engine' and also some menu where visitor have to fill questions like: what he is looking, his email, cell phone, website where he want info from, etc.
So computer program remembers this website, and when for example the house that is client looking, client get automatically email or SMS on his mobile phone, that his requirement is found.
If you know a site that is already working like this, pls also send info
