5, but a smart group will not divide it evenly. They would get what is best for the party, even it means they get nothing.
I do not see this as necessarily indicative of a "smart" group (whatever that may be). Rather, it seems indicative of either A) a group that consists entirely of Lawful characters ("needs of the many outweigh individual needs"); or B) a horribly metamaging group that will spend much time (out of character) figuring out the best way to spend the money. Here are some ideas I could think of to spend the cash, and each has its benefits. All but one (investing in a business) break the game in some way:
One group may consider it smart to spend the cash on equipping their main tank as if he were five levels higher and sending him into every random dungeon they've heard about to get
even more loot. After all, 30k gold can buy (roughly) a periapt of health +2, a cloak of resistance +2, a weapon +3 (!!!), and an armor +2 (perhaps better spent on an armor +3, shield +2, and weapon +2 if 2nd level characters are concerned). With that kind of gear (plus a small stockpile of potions), the tank is certain to wipe out every generic goblin and orc in the 100-mile radius.
Another group may consider it smart to invest in some sort of business. While it may sound like a fairly good idea, it would take YEARS for a business of this sort to pay itself off, and, frankly, the game's name is Dungeons & Dragons, not Merchants & Moneylanders.
A third group would spend the money on crafting magic items that benefit the whole group. With that kind of money, they could load up on lots and lots of potions and scrolls, thus greatly extending their fighting capabilities.
A fourth group would hire a mercenary
army and take over the entire region. Going by the current mercenary rates, they could hire as many as several hundred mercs, with higher-level captains and such.
Etc, etc. While there are certainly many roleplaying potentials in every one of the listed situations, I am not sure I'd want 2nd level characters placed in such a position that they could even
consider these options. It's your game, for sure, but you asked...
