When you buy a script from Betscripts.com you will also have full access to all installation docs, manuals and configurations docs for you to fully install and to have everything up and running with your own payment gateways in place, email settings, register settings and other related parts for the system to work.
But first, in order for you to actually be able to install the scrip we highly recommend you to go with a dedicated server,
We use CONTABO for our own scripts and if you go with the same, then simply buy the following setup option:
Dedicated server: Centos7
WHM – Cpanel
this will be well enough and you can go with the lowest disk space, and if needed you can always upgrade at any time.
