Would you ever be a surrogate?

ok so i'm thinking about it I have 2 of my own and i really do not want anymore babies. I could never give my baby up for adoption but if somebody else was to provide an embryo i wouldn't have any issues with giving baby up. I also think it would be a good way to earn allot of money while being a stay at home mum and i think i would feel good by doing such a good thing what do you think? do you have any experiences either doing it your self or have you ever had it done for you? or know anyone?
