Hi sure can take photos as per required by customer, no worries... just because since I'm not pro and also this will be my 1st time getting "paid" for photography so was a little more apprehensive on rates of course.
But anyway how does one normally charge? The fact that I will need to "travel locally" (carparks, erps, petrols) and taking mostly shots in evening period at different places...
You should an idea what is your "Over Time" rate of your day job, so the bare minimum is your wages (per hour, on site and off site), + fixed expense (your gears, hardware, software, up keeping, maintenance and etc) + variable expenses (food, transports materials etc) + a profit that you like to make = how much you should charge
on top of this rate, than you add a premium (you think you deserve it as you think you are so much better than the other guy).
everyone have work out their own rate, as this tie with their lifestyle, their skills, their self worth, so copying the rate from another photographers is not realistic as not everyone expecting the same and deliver the same.
it is just like copy answers from another student during exam, if a student don't study for the exam, he won't know are the answers he copied correct. in the end regardless passed or failed, he learn noting.
I have a feeling that the customers tell you this shoot is very straight forward, usually this can explains two things;
either they have no idea of the basic technical requirement of architectural photography, (come on, taking photos of building does not equal to architectural photography)
or they don't willing to pay much for the project.
why I say so? cause we ever see $2 architectural photography before........

so if you just want a easy way out to get back to customers about this job, just ask them how much their budget is and say "Can Do" or " "Can Not".
hope this help.
