Just because something works for someone else, it might not work for you.
Seven months is a good amount of time, assuming you are still near the beginning of the bet, though, so here is the best free advice I can give you:
Open a new file in the word processor of your choice. Go through this site, and find simple, easy to follow methods for making money, and put a one paragraph synopsis of each in your file.
Once you get 3 to 5 methods in there, STOP.
Put them in play, and work them hard for 30 days, and see how they are doing.
Take the ones that work, and make them work better. Take the ones that don't, and replace them with others.
Keep a log of how they are doing.
At any point, if you find yourself saying, well, I have spent 2 hours, and done all of the work that I can for the day, but don't see any money coming in, then you need to select methods that allow you to earn more by doing more work.
You have a target figure of just over 2K a month, and there is no shortage of posts here on methods for making ~100 bucks a day, or more, that require little to no startup capital. At that rate, 20 to 25 days a month will hit your target figure. Most of those methods require only a few hours a day, so you should be able to run at least 2 or 3 at the same time.
Best of luck.
