agree with Hart, for the pricing I see on offering or shooting blogshop shots,
don't know how can justify the time and effort, and still make a profit.
When you have too much time and not making any money, there isn't need for any justification when going cheap. Any money coming in better than nothing.
Some treat photography purely from business perspective... you pay, I click and the result is nobody business
Some treat photography purely from art perspective... you work with the photographer the way he/she wanted... if you choose the photographer based on their style, you will rewarded.
Some treat photography with balance between the two...
So it really depends on what you want.
Just to give TS some ideas, the preparation can takes a while and it won't be as straight forward as client come in to the studio and ready and you just click then miraculously the model is on the second outfit and you just click again...
The click time will be fairly quick... then the owner of the company will probably ask you for your "input" as what looks good?? see you are the photographer, you should know? its a job of stylist really.
So generally, the best way to approach is to ask questions first, then offer the quote.... what bro JasonB gives are nonetheless a good start but not the most exhaustive list to do the right thing.
To grow bigger, you can't do what everybody is doing and you can't do what you do every time... because, that means, you won't have any selling point pretty soon.
