Any tips to make some extra money?
The very best answer to this question is: take a look around your community. Is there a particular demand for needs that aren't being filled? Have you considered starting a small business on a shoestring? For example, office cleaning still remains in demand even during economic hard times.

Until you make a consistent amount of money each month, you don't need a business license to get started with an office cleaning business. For an article I recently wrote on starting an office cleaning business, go to: http://hubpages.com/hub/start-an-office-cleaning-business. For about $20 bucks for some odds and ends like cleansers, sponges, paper towels, you could be in business. It's easier than you think and with your school hours, working "after hours" doing office cleaning might just be up your alley.
