my question is, how can i become a paid shill
No experience personally but I suspect like most things you just have to be good at it and want to do it. I was a salesman early on....Lafayette Radio, TEch Hifi, Radio Shack. We were trained when someone walked in the store, your job was to find out what their problem was that brought them in and solve it for them. Worked well!! No shilling needed. Tweaks like wires were always needed and very high profit so we were trained to always make sure those were sold if people needed them. That was simple zip cord, etc. in those days. THings have gotten a bit out of hand there over time as is often the case when there are big profits to be made.
