Transfer technical data to a new InDesign template x 100

We are a manufacturing company who provide fixings to the construction industry. We have around 81- 1 sided and 5 - 2 sided A4 datasheets whose content needs to be transferred into new InDesign templates. The designs have already been created and there are existing sheets in PDF with the content required to be transferred. We would be looking to send the work in batches with an initially 3 sheets to test the quality of work. There after they will be split into 8 groups each of which will have a slightly different colour design on the template. At the moment we do not plan to request the inclusion of the images due to the work in preparing them although this may be a future second project. Attached are examples of a simple and more complex sheet along with the new design.
