It depends what you want really.
£11,000 would get you 10 days of my time.
Are you Stephen Ireland?
If I was it'd be more like £11k for 1 day.
Sadly I see nowhere near that amount, that's just how much the company I work for bill our clients for my time.
The point being web development can get very expensive depending on what you want, and as always, you generally get what you pay for.
God no wonder I am skint because that is what I do and don't charge a fraction of that. Putting together a site for what Big_John wants would not take that long as its pretty simple to do.
