I am using them for videography, more out of convenience than anything else (they have a studio in my hotel lobby)... so far they have been great with communication, and the prices seem really reasonable.
Well, I definitely have to give a shout out to my photographer, Elizabeth Medina... I don't know what your price range is, but I love her and can't say enough good things about her
There are a few other photographers in RM that are really talented and also reasonable priced. Have you looked at Claudia Rodriguez and Vanessa Vargas? A few people on BDW have used them... try doing a search for their names.
