Mounting picture frames to business office walls

We are looking for someone to mount acrylic A3 and A4 signs to our office walls. The acrylic signs have metal studs to secure to the walls. Here is an example of the sign: https://www.vistaprint.co.nz/signs-posters/acrylic-signs There are 12 x A4 signs and 2 x A3 signs for reception area to be installed. This is 1 x A3 sign for kitchen area to be installed. We listed this task two weeks ago but unfortunately we were waiting for the signs to arrive from the vendors overseas. We've received all signs except for one main sign which is currently in transit from AUS. We would like work to start w/c 9th Sept.
