Thank you for your help. I have seen all these. But our need is not to display the home. Here we trade with plots or you can say open land but in a developed society. Plot or land Sizes are generaly 4500 sq feet, 2250 sq feet, 1125 sq feet etc.
Have you visited zameen.com site. It is very easy and usefull. Please visit it. I think it is designed simply with a PHP software. Thats what I am looking for. I have browse UK2Net and selected thier Business Package. I think that is suitable for me. But if it is shared how many visitors can stay at a time on site. I think in shared hosting there is a problem when there are many visitors on site pages start getting expired.
