I’m a photographer. A potential client was recommended by a mutual friend to contact me for an event photoshoot.

Client: Hi. I’m organizing a commercial event to which I will invite some of my most important clients such as [lists some local business owners]. Would you be interested to come and shoot photos?

Me: Sure! When and where is the event?

He gave me the date.

Client: It should start at 8pm but I’d need you to be there from 7 to 11 PM.

Me: Ok. Let me check on availability and I will come back to you with a quotation.

Client: Wait. Quotation? 

Me: Yes. Quotation will establish the final price of the provided services and serve as a contract. But if you need a ballpark before agreeing, I’d say it would be about xxx€.

Client: Ridiculous! Are you really trying to make money from MY event?
