The Saberstalkers faction can be grinded for up to several hours to Revered/Exalted. The remaining two reputations for Tanaan Diplomat - Achievement do require to farm their corresponding daily quests mostly and complete the daily-unlocking quest + the new 6.2 Garrison Campaign. For the Saberstalkers I have not seen profiles so far, but for the daily and one-time quests there is profiles, both paid on the Buddy Store and free ones on the forum. Just take what best fits for yourself.
