Exactly the point, this a good advise and suggestion you got here, review campaign is better for them for now for a start more than a signature campaign, atleast this will help them get a report of how people feel about them at their website, what needed to be done, it will also give them and insight on whether to make an amendments thats outlines by the reviewer if any, these will also give there service visibility, if one should talk about signature campaign, it is about pure marketing of a brand by reputable forum members which i think they should go that lane for now because at this point some persons are still skeptical about their services, so they should prioritize review campaign first.
