to be honest just coz he's been quoted 700 doesnt mean its gonna be a crap job i'd advice seein some of his work first but in the current climate maybe he's just havin to drop his prices due to shortage of work i know as a plasterer i dropped my daily rate from 200 to 120 and on site the daily rate dropped to 80 so just see his work first and the most expensive is not always the best, sometimes people just see u comin and trust me i know, when i used to turn up at a job to price it i'd take a look at the house, car and overall appearance of the person and add pounds to the price if they looked like they wouldnt miss a few quid, everyone does it so dont go on price go on work quality!!!
