When asked to provide an estimate of an irrigation system, Pete looked from one end of the field to the other, licked a finger and held it in the air, squinted into the sun and said $25,000, give or take 30%. The technique employed for cost estimation is:

ballpark estimate

Explanation:

Ballpark estimate is rough estimate which is approximate and not actual value. This estimate is done based on the degree of knowledge and confidence levels that the estimated value falls under the range of reasonable price. This method can also be termed as rough order of magnitude.

Here Pete is an expert who has the skill to estimate the value of the irrigation system by seeing its length. He has given an approximate cost estimation for the irrigation system as $25000 which can be called as ballpark estimate.

it's actually a very difficult task, due to not many people can make 2 million dollars in 2 years. besides that, to the not-so-realistic ideas, you can create a business. it could be practically anything, but make it into a business that isn't that known yet, you get me? also, lets not forget about stock market. that's where all the good stuff happens. use investments at the beginning and begin to raise up your business or whatever you're going to do. as this is a very non-realistic idea, it's still worth the shot!
