Welcome! Have you test ridden anything yet?
Ride1up has a couple bikes that can handle light trails and fit your price range. The 700 has gotten pretty good reviews and the Lmt'd has looks promising but isn't out yet. A few folks have gotten the Gepida Fastida recently and it seems like a great value for what you get. Not really a trail bike, but should do OK on bike paths if that's more your thing. You can find the Gepida listed at Crazy Lenny's.
