It Wandered In From the Wastes

Two things for easy caps in the beginning of the game Random/stolen loot and more importantly Caravan.
There are 4 major money making spots before you get even get to New Vegas via Caravan.
Goodsprings: Random loot and Caravan with Ringo you can easily walk off with 1,000 Caps
Primm: Caravan with John Nash ... be smart about it don't sell him the random loot that you have collected in fact with the 1,000 Caps go and and buy ~700-800 Caps worth of goods from him and then Play Caravan until you have won your caps back. Clean him out of Supplies that you can sell later for profit or use to help you traverse the Wasteland. By this time your character should be Overburdened with Items so split the weight with ED-E and find one of the Trash Cans outside of the Vikki and Vance Casino and throw in the random stuff that you do not need to carry around but will sell later for a profit. Walk away from Primm with around 2,000-4,000 bottle caps.
Mojave Outpost: The Bartender will also play Caravan with you repeat the process as you did in Primm and you can Walk away with easily ~7,000 - 8,000 bottle caps.
Novac: Cliff Briscoe as with Primm and the Mojave Outpost complete the buying of goods and winning you money back via Caravan. Walk away with ~12,000-16,000 Bottle Caps depending on what he has for sale (sometimes he has 6 C4 for sale and that will bump you up close to the 16,000 range). Also in Novac you can get an apartment for only 100 bottle caps. Now you have a Head Quarters to base your smuggling of random goods out of.
Now here is why a low barter can play into your favor, and is perhaps broken but hey its an exploit that the game developers should of thought about ... So lets just say you just bought That Gun for 1400 bottle caps ... you can now sell it back to him for like 700 Bottle Caps this may seem like a waste however you always seem to win twice as much as you bet thus having a never ending supply of bottle caps. Where you can easily turn 15,000 into 50,000 and so on and so forth. However if you feel that is lame (which I do) then Just stick with buying everything and Caravaning your money back. Every time they restock you can do the same thing and before you know it you will have over 100k if you are frugal with your money.
Also it helps to sell items at places where you are idolized and you get the face value of what the weapon is worth or like 95% of the face value. remember repaired weapons can be worth an good portion like a fully repaired 10mm SMG can get you 2,300 bottle caps. Where as a nearly broken one will get you maybe 200 caps.
For those of you who say this is a tedious process well, you do it every day in real life unless you are just terrible with money. So get over yourself and learn some basic assets management.
