Luckily it rarely happens but when it does I never really know the best way to respond.
I'm a self employed photographer, been in the industry for 10 years now and don't struggle with getting business so I know my pricing is fair.
When somebody asks "what's the best price you can do this for?" how should I respond professionally?
I think sometimes people don't realise the work that goes into my job (which is the case for many small businesses) and the years of work it takes to get where I am.
