I really doubt you'll be able to find anything that's within that price range and that screen size...not new/reputable anyway. You might be able to find a something from a couple years ago, but even so it will hardly be a new unit.
The cheapest I can think of are Xiaomi's Redmi line, the Elephone, and a couple of not-so-trusted ones (Leagoo Shark and Vodafone Smart Ultra).
