I moved to Florida, USA a year ago and bought a new house. I have a couple of palm trees, as do all of the houses in the neighborhood, which are mostly filled with people who also moved to Florida recently.

The palm trees are dying, because the soil is "fill" and has next to no nutrients. A neighbor clued me in that I needed to get some palm tree-specific fertilizer, which I did, and they're doing much better now.

95% of the neighborhood has, apparently, not been clued in, or haven't done anything about it anyways. I tried to get my teenage son to do a business of fertilizing the trees for pay. I figured it was easy money and would be a good experience for him. He's not interested.

I decided to do it myself, partly for the money, but at least as much just to keep the trees from dying. I was thinking I would do some flyers in the neighborhood with my cell phone/email, and do as many trees as people will pay me to do.

I have no interest in making this anything but a neighborhood gig that, ideally, I would do every half year or so. I also intend to pay taxes on the profits (not large- I figure we're probably talking around $1k).

Do I need to set up an LLC or something? I would rather not, but I also don't want to have legal problems from something that is, at heart, more of a service project than anything.
