I would load the available manufacturers into a list and compare the contents of the textbox to the list. If it doesn't find a match, an error message is generated. Of course, you could eliminate that process altogether by providing a drop down that contains what's in the list, and allow the user to pick from the drop down, thus eliminating the chance he could enter invalid data.
