Any good 4.5+ singles ladders in orange county

im looking for some good singles competition in orange county, CA. i play ultimate tennis, but the season is too short and i dont get enough matches. i dont really like because the competition just isnt there. i play a usta team but this is the only season for singles. and i do all the tournaments i can within orange county, but one or two matches a weekend just isnt enough for good practice. does anyone play in a ladder in orange county that you dont have to be a member of the club to join. i would like to join a club, but some of the fees are just too much for someone only looking to play tennis. im not looking for a place to hang out. or if there are any TT people in orange county that are good 4.5's and wanna hit. let me know cause i am always down to play.
