Good job . In my opinion I believe your hauling 4 to 6 yards of gravel per load .Just looking at the trailer being a double axle with probably 7000 Lbs axles .It looks like your on the west coast .It can get pretty wet out that way . If you would have used a bigger unit like a dump truck you may have caused damage the existing driveway .I guess when it dried up some you wold have levelled the driveway out .And used a packer to get a good seal to the driveway . Of course this is up to the client if they are willing to pay for the costs !
The cheapest I have found was $100 to truck 25 tons of gravel 1.5 miles while putting in my pole barn. That was cheap in my area. That did not include the price of the material. He just gave me a deal that day as his truck was sitting idle at the gravel pit. I can run my dump trailer for just the price of fuel for my truck. Takes much longer obviously, but does save a ton of money on trucking.
It's way cheaper to haul it yourself. You're mostly paying for the truck to deliver it. Gravel cost almost nothing really. However, I probably would still get a dump truck if I need a lot of gravel because it would take too long in my dump trailer. For smaller jobs it's great though.
Unless you're using a dump to make money, buying one just to haul your own gravel makes NO financial sense. You can have 5 ton delivered for 50 bucks plus the cost of the gravel. You would never recoup the cost of the trailer.
Honestly, I like it way better with the music. Every now and then is fine like this video but when you're mowing or trimming it feels the need for music. And of all the lawn care channels I watch, yours always has the best music that fits perfectly in each video. You should just try and upgrade/get more cameras and maybe get a drone instead of worrying about the music. It'd be awesome to see some drone shots of your work.
