All you need to do is watch the shoddy video to get the feeling that this company is iffy. I belong to a local grotto (a caving society) and met Ryan of River and Earth while in Worley's cave. Leading a dozen or so ppl underground in a variety of clothes and shoes not suited to the environment putting them in danger. I cringed as I watched as he instructed ppl to actually touch the live formations. This is terrible to the cave environment and can actually do damage to the formations. He was not friendly when we offered a greeting and refused to speak to us as if we were not even there. But here is the kicker. Later we passed ANOTHER small paid expedition group where a member of their party had become injured (due to wearing tennis shoes and slipped). We stopped to help her out and sent for rescue. This event even made our local news. But when R&E passed by, they never stopped or offered ANY assistance WHAT-SO-EVER. He impatiently waited while we slowly moved her out of the way and then ushered his group by. Not a word did he speak. No offer to send off for help. Nothing. We sent guys ahead to call for rescue while we administered what first aid we could. They reported later that he was quite upset when the local authorities ordered the cave evacuated. Unprofessional, unsafe, and inconsiderate. There are lots of local adventure groups with qualified ppl to lead groups into caves and rafting adventures that do it for free with a much higher level of professionalism. Just search facebook or meetup.com for local caving or rafting organizations. Don't pay these guys $75 plus. Your safety is NOT their primary concern.
