Search box and results vs "enter" to go to page requested.

How can I add a box on the homepage where the consumer enters their zip code and it opens up to their local page.
On my homepage now, there is a search box but it’s a 2 step process. They enter their County now, goes to search results then to the page. I would rather eliminate the search box. Best to enter their zip code, boom, right to the page they need.
Enter LEE in the county, that’s the only County page so far.
Any suggestions to improve ? I’m sure this is simple but I’ve never needed this feature before.
