Pulse Loader How Do I Get Into Paintball Competitions?

How do i get into paintball competitions? - pulse loader

The only paintball and I bought a Spyder Electra ACS. There are some areas where people around me so I talk to them, then go when I go to a camp for some Ballin, when I got my friends.
What do I need to participate in tournaments? I do not want to spend hundreds of $ $ $ for a marker for rec.
already in Saving for a Crossfire 70/4500 nitro tank, halo b or Draxxus Pulse Loader, and a ramp tboard (i dont think ramp is allowed in the camps, but I can turn it off or limit). Overall, I think it makes a pretty decent score.
What should I know when they come into the compositions?
How do I start? How do tournaments?
