That's a simple way out. Yes, it's very easy to get answers from just "googling". Most of the time, ppl would prefer a recommendation from a friend or an acquaintance who has used the service and find it good enough to recommend it. It's just like searching for a home renovation contractor. Yes, it's easy to search the yellow pages and they have tons of them but how reliable and trustworthy are they? I am sure you would prefer someone who has done a pretty good job for a friend to be your next contractor. The same for the TS here.
