Zen cart coding work php

I have a zen cart website.

I installed numinix ultimate product fields which enables me to add unique sku fields to my products.

Its working but I need someone to code my site so the packing slips feature the sku\'s so we can pick orders from them. I think you just need to make db query to get the value I need featured on the slip..

Also it would be ideal if it was possible to be able to change the new fields in the easy populate mod so I can add and change the sku;s easily.

Thanks
