I know employing staff brings additional costs and overheads, but youre looking to make £1000 a week from one member of staff. Are you being realistic here? If that's the case all you'd need to do is employ two guys and you'd be on £100,000 a year. I know you've tried that and it didn't work for you. But perhaps thats where you're going wrong Richy. Unless someone would like to point out how Ive misunderstood this situation.
By the way I agree £18,00 a year is a fair wage but not if you are asking him to turnover £70,000 a year it isn't.
