This has been resolved on my end. As the certifier for TX having to sign off on this AND the creator of the original map it put me in a weird spot, thats for sure. I gave the measurer 2 options: draw your own maps and resubmit or pay to use the map.
My view on the 2nd option: From time to time I hire a graphic artist to assist me with maps. I pay them a rate based on their time. The graphic artist takes my template, screenshots, photos, notes etc, then draws ~ 75% of the map, then I polish it up with the measurement details and "tech specs" before I submit it. I don't see anything wrong with that as I am paying the artist for their work and I put my name on it as a representation of the measurement done. Option 2 of the is the same situation with the other measurer, except that it was submitted before any agreement to such an arrangement was made.
End result - we worked out an agreement where the time saved by the measurer by using the maps was compensated to the original artist. All is well.
