It's me that subs the work pal and I know all the prices of every house I clean for my mate. We trust each other though. Any money I collect I mark it off on my day sheet, some times it is a few quid over or under but most of the time we sort it out. It works well for us both. IMO I don't think you should sub work out to someone you can't trust with the prices. Hope that helps bud
