Exactly mate,the bigger the comm jobs your going for the more WC`s will be bidding.Just because you have massive comm jobs it dosen`t mean your earning the money it just looks good on the website,i`m not saying it`s the case with all comm jobs but these days it`s cut throat.I know a bloke that used to do colleges and schools etc in inner london,he used to go in with the pole 3 handed and get 3k for a couple of days work,those days are gone for the short term.Big firms such as OCS etc do some of these jobs for cost and in some cases at a loss just for the turnover,good on the CV not always on the bank statement.
