Opening your shop, listing products and prices takes less than 30 minutes. It costs $0.20 to list one item in your shop for 4 month (or till it sales) and Etsy takes 3.5% commission from each sale you make. Mind that fact when setting up the prices. Shipping costs are either to be covered by you or by the buyer (you can set the rates depending on the buyer’s’ location e.g. free shipping around US; $10.99 shipping to Europe).
Take advantage of your strong typing and computer skills. If you are a fast and accurate typist, if you are great at creating interesting presentations with sophisticated graphics, or if you excel at creating tables and graphs to represent data, you may be able to get paid to teach and help other students with their assignments and hone your own skills at the same time.
