The minimum requirement for that site would (in my opinion) be an EXTREMELY well tanked and piloted battlecruiser, or faction cruiser.
Much more preferable would be a well-fit battleship with sansha-specific resistances, or a shiny strategic cruiser, heavy assault ship or shudders Gila. I’ve run it before in a Muninn and with a Tengu.
If you’re set on running it, getting a group of friends together may be the best approach. Alternatively, you can sell access to the site to another interested party, this has become more complex with recent changes, here’s a video explaining it in some detail.
IMO a fair price is the cost of the overseers personal effects that the site drops (~43 mil in this case), leaving all deadspace loot and bounties to go to the buyer.
