Hi I would like to know if i will get the demo theme for the installation upon purchased?
It won’t include installation services but most themes have demo content which you can input. (Usually minus the images).
Best option is to ask the author in item comments.
You can also find freelancers to import the item and set it up via www.studio.envato.com
In case of you’d like to hire someone to perform this, I can help you:
