The cost can vary with midwives so it is best to ask a few and sus out what services they provide for their money.
My midwife cost $2200 and that included initial monthly prenatal visits at my home. Then fortnightly visits, then weekly visits (more if needed), the birth (including pool), then visits for 6 weeks after. (daily then every 2/3 days then as needed - more or less depending on your needs) She was also available 24 hours a day to answer questions and put your mind at ease or come and check you out if you are worried about something. She also provided birth education to my husband and I and went into great detail explaining how the entire birthing process works and used things like model pelvises, books, posters etc to demonstrate. Her price has now gone up and rightly so. The services she provided were worth a lot more then what she was charging. Her friendship is priceless.
To organise a homebirth you need to do the following.
1. Find an Independant homebirth midwife that you get along well with, who shares your birth philosophies and you can trust. It is essential that you are honest with each other.
2. Prepare yourself physically and mentally for a homebirth. This means educating yourself about all aspects of birth including potential problems. You need to know what you are going to do if an issue arises. What type of birth are you after, lotus birth etc.
3. Physical things you may need are support people (do you want other people to be present?), a birth space (somewhere to have the baby - do you want a pool available: may need to organise one if your midwife doesn't own one), a bucket, towels, something to protect the floor/lounge with (midwife may have these), something to hold placenta once birthed, clothes for bubs and yourself (warning you may get blood on it due to bleeding after the birth) nappies, (i found a disposable newborn nappy brilliant after the birth to catch the initial bleeding, then switched to maternity pads), breastfeedig cream such as palmers cocoa butter nipple cream or lansinoh, food that yourself, midwife and support people can eat during labour, homeopathic remedies if you desire.....
Your midwife will go through it all with you though!!

All the best with your journey!
