OK,
Where about in the UK are you? Some people like working with local people rather than remote.
You should never tell people it "should be a easy job", if it was that easy you'd do it yourself, there are a lot of resources for you to figure it out yourself.
As someone who writes software, there is a lot of debugging and testing involved with software, no matter how "simple" it might seem.
It's the same when someone asks about hardware and states "should only take you a few hours", just one of those things that annoys the crap out of me!
