Normally when you get tires put on they’ll put a new valve in the wheel, it’s pretty common for tire places to change the valves when they change the tires so not something I’d worry too much about. Get the wheels sorted out then give them to the tire place to put a tire and valve in

Last time I needed one I went along to my local tyre fitting place; one of the fitters gave me one for free

In the quantities they buy them, they likely only cost a few pence.
