I too have been trying to find an ideal location in Tampa to scale an operation, but I found a few better options.   Sago Networks in South Tampa is a miner friendly data center that will charge you electric as a pass through, so your only additional cost is the racks.  Considering it is a conditioned data center, that would solve a lot of your problems.  I was close to parking 50 miners at Sago until I stumbled on Toomim as a host, and I just had 25 come online there where I am paying 6.5 cents p/watt, which is much cheaper than 11 cents at Sago and 13 cents with TECO.  If I had 30k to invest in another 20 miners, Toomim would be my first inquiry.
