Hey @AprilRamone, welcome to the world of UAVs and to the forum; there are a lot of great people in here with experience and a helpful attitude. I own Colorado Aerial Imaging and have been flying drones in the Denver Metro area for a little over 3.5 years, primarily performing inspections. I'd be happy to help you understand the local Colorado and federal regulatory rules as well as the equipment options.
DJI owns the market share of drones in the world and they have very good products. The Mavic 2 Pro or Zoom are great drones for hobbyists and "prosumer". They cost about $1,500 without extra batteries, cases, ND filters, etc. I'm not sure what your budget is and your skill level, but you might consider finding something less expensive to learn on if don't have a lot of experience. Another option would be to contact a local American Modelers Association (AMA) club and see if you could visit their flying field and ask to fly a club member's drone at their flying field. They have wide open spaces that are legal to fly in, so you wouldn't have to worry about where to fly and you could try before you buy. Another solution would be to go to DJI Colorado, a store near Park Meadows Mall in Lone Tree, CO where they have a small indoor cage that you could fly their demo drones. The store has knowledgeable staff. The cage is pretty small, it really only allows you to get a sense for how noisy the drone is, but other than that, you're pretty limited on what the cage flying will provide for you. But, as @Philip Moore more suggested, flying over the wedding, while it's in progress, might be distracting unless you had the Zoom version which would allow you to fly higher. And as @Av8Chuck suggested, during a wedding, I think it would be difficult to transition from doing all of your normal photography shots and then transitioning to the drone. Drones are great for creating that establishing, scene setting shot, but I think your money shots are still those on the ground. So, you may want to consider adding a drone photographer, someone specifically dedicated to the drone shots to your team.
Keep in mind that in order to fly professionally, the pilot will need to have an FAA Part 107 certificate (which is not hard to get especially if you use UAV Coach as your training aid). You'll also want to have drone liability insurance and spend some time figuring out the local laws. For example, it's illegal to takeoff or land in any Denver city parks and we have quite a few airports around the Denver Metro area which puts another limit on the areas that you can fly. @Isabella | UAV Coach provided the link that has some good resources to figure out those local laws.
Feel free to reach out to me and I'll be glad to help.
