What is a legitimate plat business I could start

[Swish]

Trading people's currency in for plat coins was a legit thing back in classic on the live servers. I bound at the South Karana treants and would regularly drop in and offer people a trade...their gp/sp/cp or anything else heavy for pp.

Some didn't want to leave their camps to sell. Also I always carried extra water, sell that to people who are low for a profit lol
