They wouldn't be able to get in as Pro or Semi-Pro, for a start, and the next level is D2. As @Spikerz points out, they could probably only get a space in D3. Don't forget, this year has seen a huge turnout of teams for WC.
Also, the difference in skill level between us & them is huge - their D3 is probably equal to a CPPS D1.
Props to them for making the trip & competing. The players have probably had to dig deep in their own pockets to fund it themselves, and flights to Florida aren't as cheap as they were 10 years ago, when I used to go every year.
Once you factor in villa, car, food, entry, paint, food, buying stuff, plane ticket, food, cash for lapdances.......you're looking at the thick end of two grand. Which is a lot of cash if you're a young kid or a family man.
