house to rent for 2 weeks - sosua or puerto plata

looking to rent a house in sosua or puerto plata in february for about 2 weeks. does anyone know of  a decent place or website that won't break the bank. i checked out some sites but it was crazy the amount they were asking for. the trip is for vacation/research, we are looking to move to sosua in a year and will be going back and forth until we make the final trip. it would be great if any one could suggest a realtor in the area that would work with us.

thanks so much
