Hi there,
I live not far from this cemetery, it is really quite overgrown and in a bit of a sorry state for the most part. Most headstones are still standing, but they've not been very well looked after.
Also, it really isn't all that big, it wouldn't take long to wander round and look at all the headstones, definitely less than an hour.
If you have any more information regarding plot numbers etc. i'd be more than happy to have a walk through and see if there is anything to take a picture of for you; I have great grandparents in there too
Hope this might help you out a bit
