How much is it to bury a grandmother and grandfather there? They both was in the USA army I believe and my moms dad was a army sergeant.

To be buried there you must be a Veteran with an Honourable Discharge, Document D D 214 will secure you a Free Burial. Just because you are related to a Veteran does not qualify a burial!

I will suggest to call and talk to one of the consultant

You can also check with your local Veterans affairs and they can check on your family members service and then you can go from there. They normally will help set everything up for you. We paid nothing for my father.
