1. You could have dirty or corroded battery connections. Clean the connections first as this is the cheapest and easiest repair to make.
2. You could have a corroded battery cable. If you have a ohms meter you could check for continuity
3.you could have a stuck or defective solenoid. You could try pacing a jumper wire from the hot cable from the battery to the setter side of the solenoid. If the stater turns then the solenid is defective.
4.the starer may be sticking or defective. Take it out to a nearby autoparts store. Many of them can test the starter before you buy one.

You could have dirty or corroded battery connections . This is the first and least expensive thing to try first.
Could be a bad cable
Could be a stuck or bad soleniod. You could try jumping across to hot cable from the battery to the starter peg of the soleniod. If it  turns over, replace the solenid
May be a bad starter. Take it out to a local auto parts store and have it tested.
