in this case, would you consider POP? the population is considerably larger than sosua and it may fit a profile of your customer much better. you are probably looking for someone who is working, has a family and may simply have no time to cook something healthy. someone who needs organized and set exercise time that will fit better their working schedule. someone else mentioned aiming your business at dominicans and that sounds good: dominicans are here 100% of the time and may have less awareness of healthy lifestyle. they are also more likely to "keep up with the joneses" as image is very important here.
i know a guy who had similar business going, he would plan diet and exercise regime for people and it worked quite well for some time.
