The two most important things you will need are a ventilated (with fans) booth and an airbrush gun. You can buy both of these things online. Check out sites like Amazon (http://www.amazon.com/PAASCHE-HSSB-22-16-Paint-Spray-Booth-Airbrush-Gun/dp/B001CTC6FK) because they have a good range of sizes and prices.
