It appears aftermarket rebuilt starters retail for about 200 clams for that year and model and it sure looks like that the starter may have an integrated relay/solenoid so nothing to test there. Tack on labor to diagnose your problem and to remove and replace the starter too and thats what your looking to pay.
Now replacing a starter is not outside the realm of doing it yourself, but just getting to the point requires a set of hand tools, jacks, jack stands and/or ramps, hand cleaner and possibly a cheap repair manual for your make and model to account for the specific intricacies inherent with your make and model. Anyway, it appears there are at least 3 different starters for your year car depending on the type of transmission and you wont know what type you specfically have unless you take the old one out and compare it with the ones you might buy at Pep Boys for example.
Based on your limited experience with auto repair, you are better off calling your local mechanic to get a quote and see if they would tow your car there for free if you get the starter removed and replaced. Save yourself the trouble of getting your hands full of dirty oily grit and cut knuckles as well has having the car fall on you when you are trying to repair it.
If you are lucky there might be FAQ somewhere on some Accord Forum documentating diagnosising, removing and replacing a starter in your year honda accord. Good luck.
