It's very difficult to say what you aim for. I work on £200 a day and look for a £1000 a week. But it dosn't work like that some weeks may be as little as £500 and other weeks can be £1500.
I think it counts at the end of the year when you see how much dosh is in your pocket.
Since April i have been flat out earning well above my £1000 target a week but i know it wont last as next week isn't looking so good.
O well it usally comes good lets hope so.
If your happy with what your earning and the service your providing that is the main thing.
