I really hope you didn't pay that price, but if you did, do as Del says.
And don't get too focused on yew, there's tons of other good bow woods that are easy to find. You can probably get your hands rather easily on plum, which is an amazing bow wood as well. Straight branches 3-4 cm that offshoot from the lower stem will make great longbows or recurves.
If you need advice on European bow woods, ask away.
