davenikita2, if you have been offered a place on the undertaking that you are a self funded interational student then its an uphill struggle.
Your prospective supervisors should help you with identifying funding opportunities as this is not something easily completed from a distance and without some know how of the system.

Indeed the extra fee costs for international students is prohibitive - many come privately funded or are paid via their government and a better option may be to identify PhDs within the EU and UK which are open to international students.
