It could be a few things, but chances are it is the starter itself. When I say other things, I'm referring to things like a fuse, a relay, and so on. All of which would be less money and easier to repair.
I don't know if you have the vehicle at home at this point, but it isn't hard to check a starter. There are two wires on it. One has 12v power at all times. The smaller one only have 12v when the key is in the start position. If you have a helper, have him/her turn the key to start while you check for power. If it's there, then the starter is bad. If there is no power, then we need to check the relay and power supply.
Here is a link that explains how it's done:
