PS $10 rebuy---- help with assigning ranges

[ImOnWheels]

It's a $10 rebuy with 238831324 players. I'm pretty new at the table so no real reads on villain. We are past the rebuy period w/ avg stack being about 9k and blinds 100-200.

My stack = 6,700
Villain stack = 15,000

What is my play here? What range do you give villain? What range do I call with? What range do I push preflop?
