There are some local listings in the local paper for dancers but I'm not sure of what they will do.  I called one agency but they gave out a bit too much info over the phone so I did not see anyone - be careful.  (local paper web site is www.in-forum.com - listings under classifids).  No one from Fargo is reviewed or listed here.

There are some providers here that make periodic treks up to Fargo.  I haven't found anything locally there, and be forewarned that if you want someone to come up from the Twin Cities, that's a 3 hour drive each way.

I get to Fargo often, but I don't know of any ladies around the Fargo area.  I do know some from the Twin Cities who go up there from time to time.  If you have a free day or two, take a road trip up to Winnipeg.  I have found the services in the "Peg" to be better than most US cities.  Ladies are on time, and tend to be a great value.  Maybe not as good as Vancouver or Montreal, but better than most US cities.  Its best to exchange "US Greenbacks" for "Canadian Loonies", (The girls may not know the current exchange rate).
