When spawnd in half of it is covered in side the wall.

This is also how the spawn command works in vanilla. It will spawn relative to the player's direction. There are several things you can do to address this. First, you can be careful about the direction you are facing when running maspawn. Second, you can reposition the sign after spawning it, by updating its rotation in the data file, and then reloading the profile. Third, you can move/rotate the sign in-game with a plugin such as Telekinesis. If using Telekinesis, Monument Addons will detect the movement and automatically save it for you when you deactivate the Telekinesis tool. If using a different plugin to move the entity, you can run the masave command while aiming at the sign to save its current position and rotation to the profile's data file.

In the future, I may provide special handling for signs, to make them spawn flat against whatever surface you are looking at, to make this even easier for people.

After  I did realize I could use Telekinesis however I couldn't get the image to respawn with the loaded image. Looks like some others had this issue. 

Yes, some others had that issue, but it was a bug that I fixed in a previous release. Have you verified that the data file has the sign artist info? If it's not there, then you may be running a version of sign artist that is too old that does not have the necessary hooks. Which version of Sign Artist are you using? If it's a sufficient version (1.3.0+ for normal signs, 1.4.0+ for neon signs or pumpkins), then that means there may be a bug similar to before which I need to fix.

If this turns out to be a Sign Artist version issue, that's certainly not the first time, so I will then make changes to the instructions to help help people catch this issue on their own in the future. Please let me know which version of Sign Artist you are using so that I can determine the correct next action.

all working great!!
