I was a bit surprised to find this offer here, but it so happens that I used this macro creator recently and based on your description I should be able to achieve it quite easily.
As far as I know, copying the script for multiple computers won't be a problem at all since it's possible to export the script to the file.
It really depends on what needs to be done to say more, but as long as the macro creator is capable of it, then I should be able to do it as well.
