Not sure if its right to ask - but I will ask anyway

I am a newbie looking to start very soon - I am looking for someone who would be prepared to show me how a WFP trolley system works, how you make pure water etc etc. - would really appreciate the help from someone who has one of these systems
I am happy to work for nothing for a day or so i can gain the experience.
I live on the Beds/Bucks border (Close to Milton keynes) and happy to travel a reasonable distance.
If there is anyone prepared to help a newbie please email me
