We've just released an update which should make the process a lot more bearable.
To do so we changed daily quests into repeatable quests, meaning you can expect a new quest some time after you finished your last one (though we're not spoiling how long exactly it takes for a new quest to appear on the bulletin board ;)). Also, you now recieve significantly more reputation for finishing a repeatable quest. (from 2,5 to almost 10 times more, depending on the quest)
This won't make you instantly reach your desired reputation level, but that's the cost of keeping it balanced for any new players who get more quests and reputation from the beginning.
Hope this helps you progress even further.
Kind regards,
