i dont think it will...there has always been people starting up and then realising that in our job to succeed you need MOTIVATION , and some people just can't work for themselves...for me, its all i know iv always worked for myself, but iv seen sooooo many wc come and go, and i ends up picking up their work after they finish...
i do agree that many many people will give it a go and undercut etc...but the customer will always stick with you if you are REGULAR...
iv had someone canvassing my areas and qouting 50% less , but iv lost none ... iv been told by several of my custies that they prefer to pay me as im regular as clockwork, they trust me and thats what they need..
remember! most people have been let down in the past and when they find someone reliable they stick to them...
