As I'm sure you'd agree in your business, It's difficult to give an accurate quote, without first gaining a clear understanding of the scale and scope of a project. Your brief does have more detail than most that appear on this site, so thank you for that. But I'm going to make a guess that it should take 2-3 hours, plus travel. Based on my understanding thus far, I'll guarantee the completion of the shoot for the above quoted rate.
I am an award winning, and fully accredited professional photographer with the AIPP and ACMP. Also, as a requirement of membership with those professional industry organisations, I am properly insured for Public Liability, as well as for myself and my equipment.
So I invite you take a look at my work and to please call me on 0400 708 794, so we can discuss the best approach to achieving your portrait shoot today.
Looking forward to speaking with you soon.
Cheers....
