You can go to Macau when the 14 days stay duration expires, then re-enter for another 14 days visa free period, but you have to find a employer as soon as possible, if you travel frequently between Hong Kong and Macau, the immigration officer will notice you and make SCL on your passport, then you will have problems to enter Hong Kong.
