How much does divorce cost if I can't find him?

An uncontested divorce costs about $1500 inclusive of fees, taxes and disbursements. If you cannot locate your ex you will need to apply for permission to proceed by way of an order for Substitutional Service – which will require affidavit evidence of all efforts used to locate your spouse – typically resulting in an order that he be served by serving one of his parents or siblings. That will add additional fees, taxes and disbursements above the aforementioned costs estimate which depending on the facts in each case could add another $500 to $2000 to the total costs involved.
