Need several editable PDFs building

We are currently in the process of recreating our own style of Gas Safe certificates and other gas/electrical registration bodies. We have already had a single PDF designed and turned into an editable form however we now need to copy this style over to the other certificates and swap the fields to match the new certificates.

There are 21 in total, all will follow the same design (to be provided) and all the editable fields will need to be specifically names from a sheet that will be provided, you will just need to rebuild the layout to allow for more or less fields on the PDFs.

Once built, these will then be used in an already built application that have forms prebuilt to populate the PDF forms based on user input, so to start with we may do this one PDF at a time to ensure they are being setup correctly before continuing with the rest.
