Some of us have skills and others don't- If you are talking about servicing a car (or bike for that matter) or any aspect of Gardening then I am your man. We have a barter system of skills going in my road- And If someone else can do a job better than me- or quicker or cheaper- then we will trade skills. Last year I remade a lawn for one neighbour- Reset the gutters for another (I can take heights). while I got some labour involved on shifting 10 ton of topsoil and some tiling done.

None of us are good with tiny bits of wire or making waterproof lights- I'll buy mine and have every trust in them- and a 2 year warranty if they pack up.
