My name is Alexandra Ipate and I'm Cofounder of AA-Team (http://codecanyon.net/user/AA-Team/portfolio).
We sell a lot of plugins via Codecanyon and some themes on Themeforest. Many of our customers don't manage to install and configure the plugins / themes, 90% of the time they don't even read the documentation on how to. I recently saw that we can somehow connect our products with custom installing services via Envato Studio. It would be a great deal for us to make custom installs for clients instead of losing lots of time trying to explain how to's to clients via dashboard comments & support.
