I think it is wonderful that you are willing to do this for your friend. Knowing the pain that she would be in due to her difficulty TTC, I might suggest that you find out more details from her as to the reasons for their infertility, before offering to be a surrogate. I have had my mother and several friend offer to be a surrogate, and whilst I am very appreciative that they love me enough to do this for me, it was also extremely difficult to hear it, as it almost reinforces my fear that I will never concieve a child.
I am not yet ready to consider that this may occur, so the offer was not appropriate for me at this stage in my TTC journey and a little confronting. I hope this makes some sense.
Again, I think you are wonderful for considering this and wish your friend the best.
