Ok. That is what I’ll do. I was giving credit to the theme makers and then I stopped and only cited my own company. Now I will give both shops credit, it is just going to have to be verbose.
I always tell people that I am building a site for that I am going to use a theme and then customize that. I don’t tell them that it is a custom theme. I tell them that I am going to build a child theme. I don’t think they really care to know the difference. They just want a website.
