Best of luck to you, but I really wouldn't be mining just yet with an old gpu as you are more than likely losing money when you add in the amount of electrical cost with mining. If you don't have the money right now that isn't going to help you get the money. My advice is to stop mining until you can turn a profit, but you have the right idea by script mining as it is a little more lucrative for a longer term than SHA-256 is currently.
