It's strange that Hulu does not have all the English dub. And doing a bit of searching, I found its disputed whether or not all the episodes are dubbed. Some say the dub stops at Shippuden episode 450. Honestly, the subbed version is preferred.

Although, if you are set on the dub only, https://www.viz.com/naruto, should have dvd/digital versions for sale.
