How much money can we make in Wardogs on a $0 budget?

They finally invented Ayn Rand's Battlefield. Wardogs is the sort of huge multiplayer team battler you are familiar with, except now you have a bank balance. You earn a wad of cash with every kill, revive, heal, drop-off, or bit of construction work. Destroy a sandbag for a meagre $14. Blow up a vehicle to pocket a cool $300. Kill a person - that's $2,250. You then use that cash to buy weapons, armour, ammo, and vehicles. The profit motive drives everything.

"You have to spend money to make money," says a gruff NPC vendor, expounding the game's philosophy. Well, fuck you, shop with a mouth. We will not spend a single dollar. Instead, the Jank writers have instigated the ultimate test of tightfistedness. Which of us can make the most money in Wardogs without spending anything? Let's find out.

The rules

Our goal for this challenge is to earn as much cash as possible. We must spend $0. We are allowed five lives, and we are going in cold. That means we have not played the game before, except to do the tutorial. Less Wardogging, more Rawdogging, if you will.

This will not be easy. Even a hammer to build sandbags, or a wrench to fix vehicles can cost 50 warbucks. Reliable firearms are much dearer. Spawning a fighter jet is out of the question. Every player starts with $10,000 when they buy the game. We're not allowed to use any of it. Let's see how we get on.
