Engineer Stamp for Production Drawing

We have three production drawings where our clients require the following:

Approval signatures and the stamp signed by engineer on the
shop drawings. The documents must be signed by an engineer member of the Order of
Engineers of Quebec (OIQ), following the authentication procedures for engineering documents
established by the OIQ or any other equivalent body in Canada

The drawings are of transport carts, not super complicated. They have magnets and transponders on the base that communicate with automated guided vehicles.
