Editing closeup makro Image of an eye

I have a project right now where I could use your help with.
My clients are local photo studios which take pictures of their customers eyes to put their Iris on a black background for printing etc.

Seems like it´s a trend right here and I barealy get all my work done. So this could be a ongoing collaboration.

I allready have prepared all needed Infos on the workflow and files, like lightroom presets, black frame and PS actions that are needed to get the result my clients want. Also an example psd. with the workflow and before and after images.
The work takes me about 15-25 minutes for each pictures with this workflow.
I can pay 4$ per pictures. So I will pay 12 per hour with 3 pictures delivered.

what do you think?
