1) Pick 5 drivers. You cannot have more than 2 drivers from any category.
2) Pick a chassis and an engine. For our purposes, engine = the team, so Sauber carries a Sauber engine, Toro Rosso carries a Toro Rosso, etc.
3) Pick either a full season or half-season sponsorship. Full season costs $10 million; half season only costs $6 million but you have to renew it mid season, so your total cost is higher.
4) Total cost cannot exceed $50 million
