Couple good options in the classifieds right now that fit the bill
I would flip it around and spend $1,000 on a scope and $500-800 on a rifle. Factory rifles are amazing these days and even the cheaper models shoot amazingly well but you still gotta pay for good glass.
Tikka's are an incredible value. As for optics, what are you wanting it to do? Dialing for longer range shots? Good old 3-9? Fixed 4x?
