What to do with several lots in Sarasota & Charlotte Counties FL?

[Ahmad H.]

A relative owns multiple vacant lots (zoned for SF, between 0.2 - 0.5 acres) that were purchased at the bottom of the market in 2011, all for cash. He is at the point of evaluating what to do next. He can either sell the vacant lots or develop them and sell. 

Is there someone from that area who can help evaluate the feasibility of developing the lots and other exit strategies?
