iPhone Repairs

Can anyone assist me with where to go to get my iPhone 4 repaired as i have cracked the screen. I know you can do it through apple etc. but I am looking for a cheap and easy option. It is still usable just a pain in the backside with cracks all over the screen. Not sure if there is a previous thread as i have not really skimmed through.
Surely there is somewhere that does it fairly cheap as every 3rd iPhone i see has a cracked screen. If there isn't does someone wana sit down and nut it out, we could make a killing lol...
Any help would be great.
