Ma Tao, who started fromin the "market", naturally understands the benefits of being close to the "market" better than others.

I don't think you necessarily need to have "market" in quotations. It's not something being referred to as a "market" when it isn't; it's an actual, literal market that he's selling his vegetables at.

"If customers need fresh vegetables, we can pick them straight from the greenhouse soon and send them over.,"

If the market conditions are good, he can be the first to know and benefit the first time, which is his biggest advantage compared with other business operators.

This sounds a little more natural, and makes a bit more sense in the context.
