This subject of price is typically "what the market will bear". It's all about supply and demand. If you're in the boonies and nobody else can do what you do, you have a monopoly, you can charge whatever the customer will pay. That's often set by what kind of car the guy has sitting in his driveway, or the value of his home, etc. So, pricing can be all over the map, based on the market and customer conditions.
From a customer point of view, the price is based on the quality of the results. Demo videos online can help you prove your skill set, so the customer knows what to expect for the end result. You're a photographer. If you ask 5 photographers what they charge their customers you'll find the numbers will vary greatly, depending on their experience, skill set, notoriety and word of mouth marketing from past happy customers, as well as the market conditions.
Since you're a beginner with no certification, 333, insurance and little experience (implied by the post), you should start out modestly priced to start building your customer base. That's a good way to get good word of mouth marketing going for yourself. When you're booked with so many jobs that you can't handle it, raise your price 20%, and keep raising them until you aren't booked 3wks out, or until the FAA catches up with you
.
This summer you should be able to get a 107 cert for less than $1000. I'm hopeful the FAA will release that plan soon. That's what you need to get business insurance to fly commercial drones, if you don't plan to get a 333 (6mo waiting period) and pilot license (another 4-6mo process).
If you're in the US, and you are legally registered with the FAA, make sure you follow the guidelines you signed up to. You don't want to lose your house for the liability you're exposing to yourself to. Negligence to the guidelines won't help you in court. Keep in mine that most insurance companies will only insure you for hobby purposes. If there's an incident that's determined to be for commercial purposes (IE, you're flying for money), your insurance coverage is null and void. To get liability insurance for commercial work, no insurance company will sell you a policy unless you have a 333 and pilot's license, assuming they are a reputable company.
