Q.removal of leylandii trees
i need to get a leylandii hedge completely removed, what is the best way to have this done. i dont want any stumps remaining so will removal necessitate the stumps being ground down to prevent new shoots or regrowth. the trees are about 15ft high and 6 ft wide. will i be able to plant the same area with something more sensible in future or what would you recommend.
sorry i dont have any photo.

Getting the stumps ground down is probably the most effective way to remove them, but they can also be removed by hand with a lot of digging and chopping. In either case you can stop them from growing back. Also see this article:

As for planting afterward, adding some compost will help restore the soil fertility and help any remaining roots break down. You may want to plant the area with a legume or other "green manure" for a season to help restore the soil. Then you should be able to plant pretty much anything.
