Fiction Adaptation: Research for Locations

After writing my script and knowing what sort of location I will be looking for I then went to Ren and Mike who have lived in Maidstone for years and described what I wanted to see if they would know the place/places.
I described my church scene to them, so I need:

• A church in the middle of fields and isolated so I could see it from a distance and walk towards it as the person.
• A graveyard, this is to represent the all the dead from the war, plus I have a quick scene where Joseph walks up to a big who is crying over their relative or loved one.
• An isle to walk up as described in the script, long enough and so I can have someone at the end praying.
• To walk through/past the graveyard to the church doors and the same on the way out.

Mike was the one who came up with St.Margarets in Barming, Maidstone. So I looked this up on the internet to see pictures and where it is etc. From there  found the numbers and emails for the reverent and I contacted him to see if I could have permission to film there, I felt this is a bit of a sensitive matter as it could be disrespectful as it has a graveyard, which I do not want to see the names but if I do get them I will blur.
