Need Help finding an Angular servo

Hello,
So for my engineering 101 class we have to build a hovercraft and for steering we need angular motors with 360 degree revolution to control the propulsion fan. I am not a electronics expert. Could someone please help me find a good angular servo, on this website? I am having trouble navigating the site. Also, I need it to be relatively inexpensive, because we are broke college students. Thank you so much to whoever can help me out.

The vast majority of servos rotate 180 degrees, with a few exceptions:

]Dynamixel servos (not controlled via standard RC signals, but most can rotate up to 300 degrees):confused::m]
]Hitec HS-785HB: This motor can rotate 3.5 turns (1260 degrees). When combined with a power gearbox, you get greater torque and reduced angles:/:m]

If you are ready to consider other technology, you might take a look at a geared stepper motor.
