Hi
First of all I have extensive experience of working with professional child models, and I am going to tell you now that, legally, (and this applies to work undertaken in the USA, Canada, the UK and more), there is a requirement for the children to be licensed by the relevant authority, (in the UK the Local Education Authority where the child lives). That has to be done and any photographer, or the person employing the photographer ... in this case, you ... would break the law if that licence was not in place. In the UK it takes ten working days to get the licence.
OK, that's the legal bit out of the way.
I am due to shoot a four year old girl called Lucie who is registered with the Rebecca Middleton Agency either at her home or at my studio on an unrelated job later this month. I can add your job very easily to that requirement, so provided we can shoot both your job and that job at the same time, we can save you money.
This is one hour's work, Lucie's fee is £45 (c. $70) and my fee is £80 (c. $130) to cover the shoot, proofs delivered to you overnight following the shoot, and editing of up to ten finished images. The other $50 covers the admin costs of obtaining the licence.
I am sure you will be tempted by lower bids, but do trust me please on this that you will be opening a potential hornets' nest if you don't follow the legal requirements.
Please, at the very least, discuss the options with me.
Kind regards
