Unfortunately writing for money isn't something that is easy to do. It often takes a lot of time, effort, and even trial and error. A month isn't going to give you enough time to make a significant amount of time. To make money now rather than building up an income you can use sites like Rent-a-coder, Elance, and Guru to bid on jobs. You will need to bid low to get jobs quickly so that you can get the money coming in.
If you are wanting to make a living (at least if you live in a country where it costs a lot of money to live) and you don't want to work 24 hours a day 7 days a week you will have to build up a passive income on your writing which will take months or more. Some people work at it and never accomplish that goal.
Sorry to be the barer of bad news. Good Luck!
