Have you read "Caddy for Life" the Bruce Edwards Story? If not, its a great read, and gives a pretty good insight into the life on tour as a caddy - if you're lucky enough to get hooked up with someone as good and gracious as Tom Watson.
I guess the trick is to get a pro to give you a chance at carrying their bag. I'm not sure how you do that. For every caddy carrying a top player's bag, there are hundreds, probably just as qualified, scraping by week-to-week toting the bag of someone barely making ends meet.
The joke a few years ago was that Tiger's caddy should be included in the top ten money winners on tour. You could probably include Vijay's caddy also, however if you break down his income by hours worked he might be getting minimum wage.
