Anybody had any dealings with them?

Been asked to quote for a local factory for the THIRD time. Don't want to waste my time again 
maybe your price is to high Ian, thats one thing I hate about the three quote process, half if not more of the time the job has already gone.. but you have to be in it to win it as they say.
Sorry to jump in here; but this thing about the 'three quotes', for the last two largish jobs I've been asked to quote for, I was told that other quotes would be asked for. I didn't really need the work, so stuck a good price in there, and funnily enough I got both jobs.
I later found out that both times other window cleaners never turned up to quote, probably assuming that they too would get beaten on price.
I would say just stick a quote in that you're happy with and see what happens.
