Shovel Ready values - NJ

[Tanner Kipp]

I am a land surveyor by trade. I work for a civil engineering firm so I am very familiar with land development. I have toyed around with the idea of buying raw/vacant land, and running the site planning thru my firm, then selling that shovel ready land for a profit. My question is - does anyone have any experience doing this, or any other insight? 

The idea is that, I do this type of work all the time anyway via my firm and I have an advantage in this field due to me working in the industry and being knowledgeable in this subject. And by selling the shovel ready lot, I don't need to pony up big sums of cash or take out large construction cost loans. In theory my only costs would be purchase of the lot + associated fees, taxes, and engineering services (which I could do a portion of on my own time). 

Anyone in the NJ/PA/NY area successful with this type of endeavor?
