I thought I recalled seeing a few beginner type questions from you on other posts, but I wasn't sure. I was just felling a little worried that a completely self taught guy was out there doing tree work and perhaps in danger. Ya know, because this type of work is super dangerous. I am glad to hear you have some training and experience. Good luck and be safe!
People are the biggest danger of tree work.
Judgment doesn't come from the internet, or watching what someone else did (without insight into how and why...what's going on inside the head that you're not seeing?).
If you're not a legal biz, your customers are on the hook, probably/ possibly.
A mini will do all sorta of things. If you're not hauling offsite, or wanting millable logs, you can cut stuff smaller for a smaller mini. A full size mini can go in a trailer with brakes behind a small (1/2 ton) truck, I bet.
Mini's move stuff onsite. If all the wood went to the curb/ driveway/ other drive-up location, along with the brush, or into the woods. you get paid for more work. If you rent a chipper, you can pull the chipper and chip trailer to the work. Chips are easy to get rid off, and can be sold, sometimes, especially with time to set up the sale.
You can find someone with a spare trailer or truck who wants mulch, and have them drive their rig to the job and leave it. You blow directly into their rig, they take and unload. No hauling. Lots of people have dump trailers or regular trailers. Utility plywood and a couple 2x4s for walls are cheap, and reusable, for your friend/ buddy/ enemy/ whoever.
I still have more need at my house for chips, after moving here a year ago.
Sometimes, I'll blow chips into a trailer or service-body truck, and drop that off at a friend's, or have them pick up the trailer of chips (or logs) and unload, even-steven trade/ hookup. No extra rig or driver needed.
A serviceable trailer for a chip-trailer is an easy start, as needed. 12 years ago, I spent $300 on a trailer, added stake pockets, and still use it, one set of tires added. Drove past the guy's place where I bought it for the first time in 12 years, aftering thinking about him the other day, and taking a different route to an old customers house. I could easily sell it for $300, in no time flat. I take my mini/chipper/ trailer places that trucks won't go.
People will be more interested in having beneficial mulch if it is moved to the right spot by someone else (like with a machine). My shorter trailer (5x8x 4' sides) holds about 5 yards, and can be tipped up 40 degrees with the mini, not quite dumping, but really close, so easy to unload, especially if you can dump in several spots (so convenient for the homeowner).
For me, especially with the drought, it's often easy for me to show the customer that I CAN take all their drought-fighting, soil-enriching, competition-reducing, temperature-moderating, moisture holding organic matter to use at my house, or friends', or strangers', selling or being owed favors in the processes.
Also, I keep telling them how dehydrated their trees are. They catch on after I use the dry/ raspy/ dehydrated voice to speak as though I were their tree, many times.
I offer that I can dump chips anywhere their landscaper or they will want them stockpiled, or haul them off, as I have people begging me.
Once people realize that wood chip mulch is in demand, they sometimes don't want to pay to have a resource disposed of, and will put it to good use. Most people are ignorant about mulch.
Some simple pictures on a tablet-computer speaks volumes.
