It depends. Where do you live? Who are your clients? How complex are the projects? How big is the company? How many other staff are there?
How much business does the company do? How much do they value their employees... ;)
Sorry, I guess I should have provided more detail for this question. I'm really just looking for a general number or even a range from your experience.
Most places it probably starts off with a similar salary to middle class wages.
