You will not get any NIT or IIIT or other good government colleges with your rank in JEE mains. You can get seat allocation in some East region colleges like Gurughasi das University,Bilaspur or Tezpur University or other low rank universities. 

According to me you should try to get into some state colleges which accept JEE main ranks like Dayalbagh,Agra and AMU,Aligarh and other good universities.
