Male Infertility IVF

Hi, new to the group.
We just found out today that my husband had 1 non motile sperm which is classified as azoospermia (no sperm). We have to pay everything out of pocket and were told that IVF is probably our only option (or donor sperm). 
We want to move quickly towards the best decision since we will be paying cash & don't want to invest in plans with a low chance of working.
Can anyone shield light of their experience with something similar.
