What is done with that hole to create a properly functioning healthy environment for aquatic life requires a goodly amount of knowledge AND experience. This is, along with material costs, what you are ultimately paying for.
I second this and add: Anyone can roll boulders but will the boulders stay in place. It's also the artistry, the attention to detail, the understanding of filtration, sizing.
If you have the "shovel and a pickup" guys do your work, ask yourself will they come back when you have problems? AND what happens if someone gets hurt on the job! Do "they" have insurance? If not, you, the homeowner, WILL pay their bill.
