Looking for British Farmers – to rent open field and use tractor to Mow "I Love you" on grass?

I am looking for a British Farmer who can rent me a plot of land and help me mow the field so it reads "I Love you" when seen from a distance (or from air). I would need this for about a month.

If you have any other suggestions for my first surprise gift to my wife, please let me know. Will appreciate if its something different and really surprising (other than usual meal, spa, flowers etc).

Sky writing used to be a good way of surprising someone. If this is not possible, you could have
a banner made with your wishes,and rent a light aircraft to pull it across the sky.

Hope this is of assistance.
