IVF where to start

My sister and her hubby were just told they need IVF to conceive. They are mid 20s. They don’t have a lot of $$$ and have jobs where it will be hard to miss a lot of work for appts. I wish I could give advice but unsure where to start?

Anyone that has had IVF or knows about it what’s your advice?

Loans, credit cards?? Get a job that will cover IVF (Starbucks etc?

Any advice is appreciated
