Absolutely - Helen Benson, but it's the Gamekeepers Welfare Trust job register, not NGO. Originally I believe Helen ran it on a voluntary basis but the job register is now part of the range of services GWT provide for gamekeepers, stalkers, ghillies and their dependants.
If you've been (or may be) made redundant, the GWT can provide much more than just the job register - phone their Helpline and talk to them on 01677 470180.
So if you ring the number as advertised by the ngo does it not put you through to helen benson then?
