The United States government acknowledges your sovereignty and leaves you to your own affairs on your new territory. What do you do?
Open a liquor store that doesn't close at 2 AM.

I split it up and sell it to the market.

Attempt to relocate vital services there, such as servers for Wikileaks and/or anonymous banking, TOR, etc., sell land to any willing citizens who happen to trained as militia at a discount to non-militia & are libertarian, raise seed money for various decentralized market businesses to start there, maybe eventually get an autonomous zone going on long enough for others to see the value in attempting to start their own elsewhere in what's previously considered USA territory. I'm sure there's other important things that could be done initially, but those immediately come to mind.

Open up a bank/commodity trading store.
Druglabs and brothels!
Seriously if sovereignty was guaranteed that is what I would do.In a somewhat more realistic case to not get blockaded and invaded instantly I would probably stick to hookers, possibly some weed (maintaining a ban on exports) and try and establish a functioning offshore tax-haven jurisdiction. Unfortunately that involved a lot of restrictions on banking or your international wires will get blocked.
But one could do corporations, foundations, trusts, webhosting, some pretty decent banking and so forth.
I would probably not sell the land but just rent it to be able to keep a lid of drugs, trafficing, money laundring and that stuff that is sure to get you invaded.
I don't think such a small territory would be very successful at self-regulation these type of things, the external pressure is to high and people in business that will get you invaded tend to have some money and not really care all that much about long-term...

Open a commercial farm/zoo of endangered species.
Open a publishing firm to release the countless books, videos, and songs that are no longer in print and/or otherwise kept artificially high due to IP laws.
Lease out parcels of the land to corporations wanting to use the territory as a tax haven, this should provide a more than substantial income for my personal expenses.
Sell nobility titles on the internet.
Design a suitable flag.
And, assuming that this piece of land borders water and has the necessaries, begin work on a port for trade.
