vehicle selector

We are running a bigcommerce store. we sell performance car parts and are in need of a drop down menu to filter out parts by vehicle year make and model. I want the customer to be able to select their cars year make and model and then it pull up all the categories that contain products that will fit that vehicle. Magento and other shopping cart software providers have add ons that can be purchased to do this task, but big commerce does not. i will need it developed and installed on our site. if you can modify existing programing or scripts to make this work on big commerce is fine. I just want this feature on our site. We are looking to hire for other projects like template design changes as well so if this goes well there will be plenty of work in the future as we continue to develop this site and others.
