Charity Walk around Britain 2009

Firstly, I want to thank the webmaster for assisting me to get back into this Forum. I posted about a year and a bit ago, and below is somewhat similar to then, because what I was trying then had to be postponed.
In short, a friend and I (he from Hereford and myself from New Zealand) have had quadruple heart bypass surgery. We want to contribute back to society, and thus we've organised a walk around Britain by the 2 of us with a car/caravan and driver.
The walk will be London to London, around Britain (but not around the coastline), some 2,500 miles (4,000 kilometres) from 29 April to 24 September 2009. (I'm trying to get a charity team entry in the London Marathon on 26 April 2009, mainly for publicity purposes for the charity walk.
The 2 charities to benefit will be The British Heart Foundation and the Rett Syndrome Association UK, and we hope we can raise a minimum of £100,000 between the 2 charities.
What we seek is a free camping site for our caravan in or nearby Newtonhill for the night of 14 June 2009. Anywhere will do us, as we will arrive from Inverbervie somewhere about 6 pm and depart again for Balmedie about 8.30 am the following day. Our requirements are minimum.
See http://charitywalk2009Britain.blogspot.com for the details of our itinerary, and check the places where we have confirmed free sites so far, and where we still seek sites.
I wonder whether any of the readers of this posting can help me in this as regards Newtonhill, please, and also help me to find contacts in any of the towns on our itinerary where we seek sites, particularly Inverbervie for the nights of 12 and 13 June, and Balmedie for the night of 15 June. The reason for 2 nights at one site is that we need to allow a non-walking day every 5 days or so.
I can be contacted at xtr208758@xtra.co.nz and I will send free copies of PDF file of the book I'm writing about all of this. It's in draft, of course, but I'm into Chapter 29 and at page 136 so far.
