Surrogate looking to fund Gay couple

Mu name is Monique and I am raising fund for my brother Marc and his partner Claude. They have been trying for years to become parents and have used various agencies, contacted various countries and have had absolutely zero success. I have offered to assist and be their surrogate :-) I have two kids of my own and I am excited about the fact that I will still be part of the little ones life after birth, not as a mother but as an aunt. We need to have the insemination done next week as this is when I am ovulating and need to pay the clinic R80 000 (equal to $5527.09) My brother will be leaving in 2 weeks to go to Uganda for work and will stay there for 3 months. Because their journey has been delayed so long already I would like to do this for them as soon as possible...
