Dear Eka,
Thanks for your e-mail and best wishes
We are extremely delighted with this news and we hope and pray that everything goes smooth from now onward and our SM will be able to achieve a successful pregnancy with healthy babies.    
Throughout this duration, you have been extremely professional and caring. Thanks for your efforts and emotions which you have extended toward us during this short period of time.   
I will definitely let you know if we decide to go for another surrogacy programs in future. May God ease our journey from now onwards without any hiccups. 
With best regards,
N and N
