I am sorry you are going through the "traditional" dilemma. No funding means no PhD. In this stage of research where you are starting your career in research by pursuing a PhD, it should not be expected from you to find the funding. If the supervisor accepted you on condition you will find funding, it does not look for me like a real acceptance. If I were you, I would search for another opportunity and do not waste my time with this supervisor. It is like getting a job offer which states you are not going to get a salary unless you directly bring profit to the company.
