Online Business Data Count Tool

Hello I need a web based? business data count tool developing. An example of something similar can be seen here? <[login to view URL]> The visitor can search for business data and narrow down their search by using various search criteria. For example, by Geographical region, Business? Type, Business Size,? etc, etc. After the visitor has carried out their search using their specific criteria the tool will count the results and tell you how many records match your search criteria. However, this? particular example site has the problem that it can only be used in Internet Explorer. If possible, we need a tool developing that will be compatible with other browsers as well such as Firefox. Please give your suggestions how this can be achieved. Ideally, I would like this developed within 2? or 3 weeks, but will consider a longer period if necessary. I have attached a sample of the business data records that we will be using. The total number of business records may be several million - approximately 2 - 3? million. Also, attached is a 'counter selection criteria' document with the types of user selectors that we will want - for example, Geography, Type Of Business, Business Size, Attributes. The site will be hosted on a unix server - php / mysl The front end of the site can have a basic design, as we can change the graphical design of it ourselves later. We are interested in the functionality of the count tool.
