Autocomplete Textbox in form for ASP Classic page

I have asp classic page - need to add a selection method where a user can start typing name in a text box - and have the box (or pop a box with small list of close options) display the match. The list will come from a MS SQL data list of name - could have up to 2000 - 3000 in the list and we have to be sure this is very quick and responsive. Any questions let me know
