Your job is what someone is willing to pay. You have a lot of good thoughts above, some of which I don't have time to read but some jumped out at me as good advice.
Basically; you want to charge as much as you can while making the person you are giving them a good deal. Your also going to want to build this business. I assume...
Let's say your willing to do a 60 min shoot (on site for an hour) that will include about 30 min of air time and 30 min of prep for setup, landscape, obstacles and weather analysis.
You will provide an edited video with 10-15 min of footage along with 15-20 still photos and all of your rights will be waived to the licensing of the photos and videos. So by purchasing, the customer essentially owns the photos.
Say you will travel up to 30 miles in each direction included in the fee.
Toss out a number like; $250 and say it's that low because your starting out.
Finally to get this deal done; tell them you will give a 50% discount if they provide a referral or statement on your website or Yelp or Facebook or something visible. Last, say you will give them a $20 referral fee for all jobs they pass onto you via word of mouth.
You will accomplish:
1) initial sale
2) understanding of fair market price
3) positive reviews
4) referral stream
If you find that $250 is pissing people off; your high. If it's taken too easily, raise you fee.
If people want more air time, more than 10-15 min of video, more than 15-20 photos or want you to travel more than 60 miles you will have a price rare card to tack on in order to properly compensate you.
On yea, and make sure you do a good job.
