4) reduce your groceries and clothing budgets -You don't need to spend $12,000 a year on clothes 
5) cancel life insurance -You don't need it any more, you have enough assets to cover all debts if you should suddenly pass-away and still have something for your kids and to roll-up your corporation (you only need about $10,000 to roll-up a corporation)
