In Cabarete the Callahon opposite dream condos main entrance there is a road headed toward the mountain view. you go to the first street in and turn left for about 30 seconds on your right you will friend what you are looking for if this is closer than charimicos for you
There is a Canadian across from the little playero ( Sousa ) that has a work shop behind the motercycle place. I believe his name is Richard. I believe he does alot of metal art work and might have what you need. I will see if i can find his card.
