When looking to use subs what mistakes have you made? What critical things should be done? Getting a lot of phone calls recently and I've got a couple of guys I've worked with previously who are now out on their own. I'm looking to use them on splash backs first to see how it goes. But have a large job coming up that I will need then on. Obviously a contract will be written up but if there any other points I should be made aware of? Cheers lads
