Hiya!
Ummm...keep adventuring? If you are thinking in terms of some wierd "business venture" thing...maybe starting an "Adventurers Guild" or "Adventuring Company". Get a 'guild hall', hire some accountants, recruiters and info-gatherers, start charging dues, send out teams of adventurers to do tasks, etc. *shrug* Why an adventurer would pay another adventurer to go adventuring doesn't make much sense, however.
Now, some kind of "adventure information broker"...that could work. Adventurers who's main goal is to find info on lost dungeons, ruined castles, extra-planar treasure cache's, brewing conflicts between two groups, etc...and then selling that info to the highest bidder. That might be workable (and believable).
