Paintball Party At Home?

I want to have a cookout, and throw my son a paintball party here at our home. We live on four acres so there`s plenty of room to have a blast. The only problem is I can`t find anyone that rents the equipment and will bring it to my home, or if I can even afford it. It this idea doesn`t pan out, I don`t know what to do for about 25 10-11 year olds. I know I DO NOT want to have to transport them anywhere because we live over an hour away from DFW. I feel stuck between a rock and a hard spot.
