The nursery folks will provide a written quotation which will outline what is to be done and they will guarantee their work.

Me? I would hire a couple of local teenagers and supervise the work and pay them cash as long as their parents agreed it was okay.

I was mowing lawns, trimming hedges, shovelling manure and snow... at 12 years old. I put myself through university and it was because I did shit jobs for FAR LESS than any minimum wage. Back then, we didn't have high unemployment and we didn't have illegal aliens because we had youths that actually got off their asses and did work for elderly people at a price they could afford.

I would go on but youse get the idea. There is no sense of hard work or of community anymore... just laziness and "what can I getout of it?"

Hire a kid or two and be done with it.
