Crab,
Perhaps if you can spare 20mins of your time, you could pop down and talk to them. While doing this you could check them out to see if they are good enough to fit into your plan. I expect the DAAT could let you have the 5% of Devon they are unable to cover in 5 minutes, although you may have to reposition yourselves to be able to respond in time!
While you are there, would you like to pick up an Anaphylaxis kit just incase that bee in your bonnet turns nasty and stings you!!
