hay Chaps, im shore this has been coverd plenty of times... but how hard is it to acturly fit Coilovers?

i have a basic idea on how to fit them, im pretty good with tools, have time, and love a challenge.
iv had a few mates offer me to let thm do it for a few quid, but tbh id enjoy just to try and fit thm myself over a weekend or sumit.
im going to buy the FK AK Streetline Coilovers, there like 180quid. Perfect for starters i thought.
Any help much appreciated and any links i can follow to?
Thanks Phil
