Well the traditional values for chips are:
But you can make chips worth any amount you want really.
You can start with $1000 chips if you like, or even start with $100 worth or even $10,000 if you feel like it (or have enough chips).
To start blinds, you usually start the big blind at 1/100 or 1/50 of the starting stack. So if you started with $1000 in chips, the BB would be $10 or $20(SB= $5 or $10).
And if you started at $10,000 chips, the BB would be $100 (SB= $50) or $200 (SB = $100)
