OK, I need a bit of advice (so I'm probably in the wrong place, bet here goes anyway)



I want to render all the walls around my garden - I am a DIY nightmare, but generally enjoy fucking things up and like to get the whole family involved as well.

I would like to know...

What materials and tools I would need
Approximate cost per square metre (or per meter length of wall) for materials
A step by step guide to doing it

Or would I be better off just getting someone who knows what they're doing - if so, what would I expect to pay (again, per square metre)
