Be careful to choose maid as you are both working. Not to make a hasty decision otherwise it will end up in the same way as you are now. Employ a part time hk domestic helper to help you with the work. There is a government agency for hk domestic helper call employment retraining centre--check the directly and give them your requirements, they can help you. About your maid now, please ensure that she will not steal any valuables from your house and all recipts of payments of salary and air ticket are received. Of course dont forget the resignation letter. All should be faxed to the immigration department and the consulate for records and information.
Last thing and I hope it would not come to you is the calls from other maids or financial institutions about debts from your maid. Good luck
