Here's a quick and dirty answer. It won't be completely accurate but it will give you an idea what to expect:
If you are only playing positive counts at a game where the players are playing about 60 hands per hour you can expect to play about 60*.25=15 hands. With an average bet of around $40 you can expect about $40*15=$600 worth of action every hour. Assuming a 1% win rate you can expect to win about $6 per hour.
If you can find a game where they play 100 hands per hour (or walk away from extremely negative counts to check other tables) you may be able to play about 25 hands per hour and earn $10 per hour.
I'm sure someone will give you some more accurate answers than this, but hopefully this will give you a ballpark idea.
