Ajax Magento Vehicle Selector

We are looking for someone to build a Magento Module that allows the front end user to search for a year make and model of a car and it would filter the products attributes to find the matching products. Also we would want it to use attributes such as "start_year" and "end_year" but have the module fill in the years between. These would also have to match multiple products and we would need it to be loaded with Ajax to help the load speed of the webpage. I would like to complete this project asap and would need it to work in at least Magento Community 1.5.1.
