Customized calculator for Wordpress page

Hello, I have a wordpress page which compares different options to donate money to non-profit organizations. I have a database (excel) with different kind of information on each organization. I would like to transform this data into a calculator for my page so that visitors can calculate which organization fits best their needs. The data is either yes/no (e.g. does the organization support children in need) or ranges (e.g. minimum donation per months per organization). As user of my page = of the calculator, you should be able to select the categories or with a scroll bar select the range. Then it should show immediately how many and which organizations fulfil the criteria (as a simple list with link to the detail pages of the organization). The user can either select on one or on a combination of several categories. In the back end, I can input the data of the organizations and add / delete new categories. There are always only two types of categories (see above). Finally, the calculator should have the look and feel of my page (very simple, not much effort should be used for this steps). And I need to be able to include this calculator easily into my wordpress page. You may use existing widgets / programs etc. for this, of course.
