Pull the starter and take it to a LOCAL rebuilder of starters and have them check it out for you ( usually at no charge) if your starter is no good then have them build you a starter and explain to them what you are useing it on and will get a starter that will turn the car over when you turn the key.....thats what i did and my current starter is 9 years old and still works better than any off the shelf starter...
as for the possibility of teeth being gone from the flywheel.....put a socket on the crank bolt and turn it over by hand with a light look through the starter mount hole and inspect your flywheel ring gear to see if the teeth are good.....if you have teeth missing your going to replace the ring gear....if you have a couple that are just chipped on the outer edge then you may be able to clean up the rough edges with a file...if your lucky.
