My client started his own vending machine company teaching others how to make money with vending machines. He wanted to offer his clients a site for their business and asked me to make a demo / mockup site to show to his clients. Having another site he wanted me to mimic, I setup a WordPress site using Divi and created his demo only better looking.
We worked out a pretty sweet deal for both of us. I gave him a great price on his demo and he would send me any new clients for their copy of the site. Thanks to WordPress and Divi setting up his clients with a similar site to the demo saves me a lot of work and allows him to offer his clients a great price as well. Another happy client!
