Simple cartoon image

Hello. I need 1 x simple cartoon image, to depict a Health & Safety scenario, as follows:

'A woman standing on a swivel chair reaching to put a box on top of a cabinet at a dangerous angle'

My client has already had some cartoon work produced before, and would like to keep this piece in a similar style - please see attached. Also I can provide some guidance on the image composition.

I think in the first instance a sketch would be great. This can be sent on to my client for approval/comment. Once approved, I would like the final piece in a digital format (*.eps or similar). We will need 100% copyright post completion.

There will be a further 5 images to be created once this first image has been approved, all at a similar level of complexity.

Please advise on a fixed price for one image.

Ideally I need to get a sketch of this first image to my client for late Friday, but I appreciate that may not be viable. Please advise on turn around time/schedule.

Thanks.
