Thinking about next year and looking at taking the next step and getting some help , just after a bit of advice from people who have , trying to work out how much of a mark up I need to put on each plumber in order to pay there wage and still make it worth while for me without pricing myself out of jobs . I've got a tiler at the moment subby and make about £60 a day out of him , not a lot I know but he turns up knows what he's doing and I don't get any grief , I've heard before that in order for you to come off the tools (eventual goal ) you need around 5 plumbers to make it work ?? Any thoughts ??
