Hola from Cancun Spike,
If you wish to dive this area privately for the a lower price than the company you mention per diver, click on the website below or shoot me an email or a PM,for a totally private integral service, we as well have you dive only what you wish and not push any dive packages.
Some dive ops offer a personalized service but if you are not a group of 6 you will have to dive with other divers with different experience level, we provide a totally private service, meaning that if you are 1 or 2 divers or a group you will dive only with your group and one of our dive masters or instructors, we may have other divers on board with their own guides, but you will be diving exclusively with your group even if you are only 1 diver you are taken privately for the same or lower price. We do not claim we know exactly what you need, our experience diving the area has showed us every diver has different needs and only when we get to know you and your diving experience and what you wish to do is when we can build together a dive package or even just a dive exclusively for you. (on the website can also check our trip advisor comments, all of them and here on scuba board are real from divers that are now friends and not from payed help)
HAPPY DIVING
