Marines mean Business - it provides wealth of unique experiences and leadership opportunities [19]
Overall a well-written essay. The only major criticism I can think of is that you don't really talk about how becoming a business student relates to your goals, though one can assume you believe the education will help you in your endeavors to grow your family business.
As to how you can cut it down to size, you could try breaking it up into two essays, one about your time in the Marines and one about your challenge in starting up a new business. Connecting the two is sort of neat, but it does take up room. Most applications have an extra, optional essay you can write to cover anything you couldn't work in to the mandatory ones, so you could use one essay for that and the other for this.
Alternatively, you could try condensing the second paragraph into one or two sentences, and merging them with the third paragraph. You service in the Marines is admirable. Your ability to deal creatively with the challenges of starting a new business is likewise admirable. Carrying out the basic work of setting up the business for opening day is neat, but it doesn't grip the reader with a sense of your brilliance, so if you have to cut something, this is where you would start.
Some very minor grammatical points:
"commitment
, and loyalty"
"I came home and was informed by my parents of
their desire to start up a new business."
"to grow it from
the ground up into the thriving business it is today"
"and had a
friend's printing company make me 4000 copies"
"my business and would
sign for and inventory packages, and notify recipients" I'm sure you weren't actually inventorying the recipients :-)
"More important than the funds received from the condo association, was the exposure from handling packaging for 600 units." Omit the comma in this sentence.
