Soda machine

I'm wondering if anyone could help build a touch screen soda machine. Using the touch screen to control three mini air pumps. Another criteria it has to autonomous and hook up to a USB port for power. Any help is greatly appreciated.

Touch screen: No a problem. Plenty available. Typically 2.8", 3.5", or 4.3" diagonal. Do you have one in mind?
Control three mini air pumps: No problem. A single MOSFET each will turn DC-powered pumps on and off.
Has to autonomous: No problem. The Arduino can control motors without the help of a PC or human
Hook up to USB port for power: No problem for the Arduino. Might be a problem if that USB port has to power the mini air pumps. Do you have a particular mini air pump in mind?
