Looking for Junior Tennis Player Matches

My son is a Junior USTA competitive tennis player and I am looking for matches for him for 12 and Under.  We are vacationing in Redondo Beach and he would love to play some matches while we are here.  He usually plays with the green dot balls for USTA tournaments, but can play with the regular ball also.  I am also a 4.0 player and would love to play as well.  We will be here until June 2.
