Can i make a consistent income playing blackjack and how much?

I am a college kid that lives an hour away from casinos. I have aways played blackjack even as a young kid on the handheld games for fun so I have basic strategy down. I usually play till I win 150 bucks. I do this twice a week because I work the 5 days a week. I quit if I lose 50 bucks. I am not looking to make a ton of money doing this but a college kid making 150 bucks for 4 hours of work isn't bad. How much can I possibly make in a night? Hey an extra 300 bucks a week is nice even 200 because hey that's a car payment.
