New Hydroponic Business

I also posted this thread in the Hydroponic Gardening forum.
My boyfriend and I live on a family owned and operated farm. We are in the process of starting our own hydro farm and have been seeing a lot of data saying that most hydro farms fail within the first two years. The data seems to be 2-5 years old, so I'm wondering if this is still the case. If it is, why is this so? We would both like to farm full-time, within the next two years, but the marketing side of things seems a bit overwhelming.

My goal is to sell $8000, worth of produce on a monthly basis. I know this a tall order, but I also believe it can be done. There are no farms of this type within a 100 mile radius of us, plus we are within one hour of Chicago, Rockford, DeKalb, and Centeral Illinois. I feel our marketable area is, not only extremely large, but diverse.

I would appreciate any thoughts you all have on the business side of things, marketing, and maybe to help me see where I can potentially fail as a business owner. I want to come into this with a full understanding of the risks, problems, and potential of every aspect of owning a hydro farm. Also, have any of you attempted or currently employ aquaculture? I'd like to eventually do some of that as well.
