Table schema:
CREATE TABLE table_name_73 (founded VARCHAR, first_af2_season VARCHAR, final_af2_season VARCHAR, arena VARCHAR)

Question: How many founded years had a final af2 season prior to 2009 where the arena was the bi-lo center and the first af2 season was prior to 2000?
SQL: SELECT COUNT(founded) FROM table_name_73 WHERE final_af2_season < 2009 AND arena = "bi-lo center" AND first_af2_season < 2000
