Photographer Contingency Plan

Hi, all so I am officially in the throes of planning a wedding and we are now selecting photographers and videographers. My partner and I have narrowed it down to 3 choices. One of which seems very polished, professional and capable of doing a good job but not necessarily the best fit for us. The second choice is very professional, does great editing and has the highest price point of the 3. The third option is the cheapest option but doesn't seem as polished or professional. However, their work speaks for itself. They create both incredible photography and videography at a margin of the cost. One of the reasons I'm led to believe this is because they are a little bit newer to the field and also do not seem to be fully tapped in to the wedding market.


Therein lies my concern. When talking with this option, the third option that we like the best, We asked point blank what is your backup plan in the event that you are unable to shoot our wedding?
Their response, that has never happened and we would do anything we could to make sure we'd be there. However, that was not the answer We were looking for most other people we have met with have Been very clear that it's built into the contract that if they cannot make the wedding, they will find an additional photographer for us.
How can we articulate our concerns to this photographer? In a way that ensures they understand the severity of our anxiety around something going arwy that is completely preventable. Or would you recommend just going with one of the more seasoned professionals at a higher price point?
