Finding work in the DR

Hello!

I am planning on moving to the Dominican Republic from the U.S. in a month or so.  I am trying to find out more information on working in the country as a foreigner.  I know in other countries you have to have been a resident for a certain amount of time.  Is it like that in the DR?  Does an expat need a work permit to legally get a job?  I would appreciate any information anyone has.  I will probably be living in or around the Santo Domingo area. 

Any other tips on finding places to live would be very helpful as well!  Thanks!!
