Just starting out

Hey, Im recently getting into GHL and was wondering if I should offer ads to business that I pitch this to and if so Should I also Include selling Ai voices and chat bots and if so if you guys have any tips. Also I was wondering about the ease of setting up a workflow is and also if GHL is usable on the app and which tier of GHL I should purchase. If you guys have any tips or tricks that would be very much appreciated.
