Here's where you can go to find PDGA money and point totals for 2008. You can even break it down to by classification, age bracket, gender, state, etc.

Here's some statistics you might find interesting:
298 PDGA pros (271 men and 27 women) made at least $1,000 playing disc golf last year.
144 of them (130 men and 14 women) made at least $2,000.
91 of them (84 men and 7 women) made at least $3,000.
65 of them (59 men and 6 women) made at least $4,000.
49 of them (44 men and 5 women) made at least $5,000.
31 of them (27 men and 4 women) made at least $7,500.
20 of them (18 men and 2 women) made at least $10,000.
8 of them (7 men and 1 woman) made at least $15,000.
5 of them (all men) made at least $20,000.
3 of them made at least $30,000.
None of them made $40,000.
And note, these are
gross earnings, not net. I'm sure some of these people are getting some degree of tourney entries paid for by their sponsors (namely the people at the top of those lists), but as you get lower and lower down, those folks are more than likely paying a better percentage of their tourney expenses out of their own pockets.
You can probably count the number of people who play disc golf exclusively for a living on one hand, give or take a finger.
