I have gone through those profiles in your search results and non of them suit my test, because they  are just claiming to offer wallets recovering services with no proof of work. And the funny thing there is those profiles claiming to offer wallets recovering services are already red taged that's to tell you that they are scammers, but that's by the way.  As for Wallet Recovery Services - KeychainX I think I have came across there thread in one of this boards, and  I have made few comments there and also asked there representative few questions that is yet to be answered, because am not still satisfied with what I have read from there source link provided by there representative.
