Design a great looking CSS/HTML search box widget

I want a small widget based off CSS and HTML that displays a very nice looking search box and drop down menu with a submit button. The size should be small, around 250 pixels wide, and about 150 pixels high (approximately). A user will enter a zip code or city in the text box, select and item in the drop down menu, and click the submit button and be redirected based on his choice. I will send you more specific details on the options and our website and how it should look with the winning bidder. It must look VERY PROFESSIONAL.
