WordPress plugin for autocomplete textbox

I am looking for a bit of code to add to my website called Workwear Wizzard, I use word-press for the website. The idea is that I can load in products and tag them or profile them, I would need a search bar and a small image like a wizards hat with builders stuff on, I can do this, then the sear next to it with (what are you looking for), When you start to type for trousers it will start to list trousers as a search result, when the trousers has appeared you can click on it. When you have selected trousers (for example) it will then ask you what is your industry, then it will list different industries, like Electrical, the next step will be another option such as, heavy duty, inside or out, these items are controllable by what ever I put in, I then get the option to list the results on a page with a few options. (maybe if it is a plugin i can just go to the plugin page and edit what i want to appear in the boxes) If that sounds ok I could do a layout of what I would like it to look like and work like too. I would like it to almost at that point be a comparison site for products and prices
